cmdutil: remove the redundant commit during amend

There was an extra commit made during the amend operation to track the
changes to the working copy. However, this logic was written a long time back
and newer API's make this extra commit redundant. Therefore, I am removing the
extra commit. After this change, I noticed that

  - Execution time of the cmdutil.amend improved by over 40%.
  - Execution time of "hg commit --amend" improved by over 20%.

Test Plan:
I ensured that the all the hg tests passed after the change. I had
to fix a few tests which were aware of the extra commit made during the amend.

 Issue 3445: amending with --close-branch a commit that created a new head should fail
 This shouldn't be possible:

   $ hg ci --amend --close-branch -m 'closing'
   abort: can only close branch heads

 This silliness fails:

 Check that amend properly preserve rename from directory rename (issue-4516)
 
 If a parent of the merge renames a full directory, any files added to the old
 directory in the other parent will be renamed to the new directory. For some
 reason, the rename metadata was when amending such merge. This test ensure we
 do not regress. We have a dedicated repo because it needs a setup with renamed
 directory)

 Test amend with file inclusion options
 --------------------------------------
 
 These tests ensure that we are always amending some files that were part of the
 pre-amend commit. We want to test that the remaining files in the pre-amend
 commit were not changed in the amended commit. We do so by performing a diff of
 the amended commit against its parent commit.

 Editing a hunk puts you back on that hunk when done editing (issue5041)
 To do that, we change two lines in a file, pretend to edit the second line,
 exit, toggle the line selected at the end of the edit and commit.
 The first line should be recorded if we were put on the second line at the end
 of the edit.

 Testing the review option. The entire final filtered patch should show
 up in the editor and be editable. We will unselect the second file and
 the first hunk of the third file. During review, we will decide that
 "lower" sounds better than "bottom", and the final commit should
 reflect this edition.

 Check ui.interface logic for the chunkselector
 
 The default interface is text
   $ cp $HGRCPATH.pretest $HGRCPATH
   $ chunkselectorinterface() {
   > $PYTHON <<EOF
   > from mercurial import hg, ui;\
   > repo = hg.repository(ui.ui.load(), ".");\
   > print(repo.ui.interface("chunkselector"))
   > EOF
   > }
   $ chunkselectorinterface
   text
 
 If only the default is set, we'll use that for the feature, too
   $ cp $HGRCPATH.pretest $HGRCPATH
   $ cat <<EOF >> $HGRCPATH
   > [ui]
   > interface = curses
   > EOF
   $ chunkselectorinterface

 It is possible to override the default interface with a feature specific
 interface
   $ cp $HGRCPATH.pretest $HGRCPATH
   $ cat <<EOF >> $HGRCPATH
   > [ui]
   > interface = text
   > interface.chunkselector = curses

   > interface.chunkselector = text
   > EOF
 
   $ chunkselectorinterface

 If a bad interface name is given, we use the default value (with a nice
 error message to suggest that the configuration needs to be fixed)

 Changeset reordering
 -------------------------------------------
 
 If a secret changeset is put before a draft one, all descendant should be secret.
 It seems more important to present the secret phase.
 
   $ cp -R base reorder
   $ cd reorder
   $ hg histedit -r 'b449568bf7fc' --commands - << EOF
   > pick b449568bf7fc 11 f

 Changeset folding
 -------------------------------------------
 
 Folding a secret changeset with a draft one turn the result secret (again,
 better safe than sorry). Folding between same phase changeset still works
 
 Note that there is a few reordering in this series for more extensive test
 
   $ cp -R base folding
   $ cd folding

 Check abort behavior
 -------------------------------------------
 
 We checks that abort properly clean the repository so the same histedit can be
 attempted later.
 
   $ cp -R base abort
   $ cd abort
   $ hg histedit -r 'b449568bf7fc' --commands - << EOF
