test-resolve: add test resolving one of two files

The tests for resolve are missing a lot of cases. Let's start by
adding another file to the test repo, so we can test resolving one of
two files.

 test that a commit clears the merge state.
 
   $ hg init repo

 create a second head

 failing merge
 
   $ hg merge --tool=internal:fail
-  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
+  0 files updated, 0 files merged, 0 files removed, 2 files unresolved
   use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon

 resolving an unknown path should emit a warning

 resolve the failure
