amend: do not traceback on no-ops

If rewrite() generated changeset happened to be an existing one, the
call would traceback when trying to obsolete the changeset with itself.
Instead, leave gracefully, marking any intermediate changeset extinct.

Test amend captures branches

  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ hg amend
  $ hg branch
  foo
  $ hg branches

Test collapsing into an existing revision, no intermediate revision.
