test-status: add test for removed-and-untracked state (BC)

In Mercurial 3.0, "hg status" can list the same file twice if it was removed
but still exists in working directory, i.e. removed by "hg forget":

  $ hg status --rev 0 removed
  R removed
  ? removed

But since 65cdc6bab91e, untracked state, "?", is no longer displayed in this
example.

I think the new behavior is correct since a file should have single state, but
if it is a bug, this patch should be dropped.

 test "hg status" with "directory pattern" which matches against files
 only known on target revision.
 
   $ hg init repo6
   $ cd repo6
 
   $ echo a > a.txt
   $ hg add a.txt
   $ hg commit -m '#0'
   $ mkdir -p 1/2/3/4/5
   $ echo b > 1/2/3/4/5/b.txt
   $ hg add 1/2/3/4/5/b.txt
   $ hg commit -m '#1'
 
   $ hg update -C 0 > /dev/null
   $ hg status -A
   C a.txt
 
 the directory matching against specified pattern should be removed,
 because directory existence prevents 'dirstate.walk()' from showing
 warning message about such pattern.
