checkcopies: add a sanity check against false-positive copies
When grafting a copy backwards through a rename, a copy is wrongly detected,
which causes the graft to be applied inappropriately, in a destructive way.
Make sure that the old file name really exists in the common ancestor,
and bail out if it doesn't.
This fixes the aggravated case of bug 5343, although the basic issue
(failure to duplicate the copy information) still occurs.

Our full contribution guidelines are in our wiki, please see: https://www.mercurial-scm.org/wiki/ContributingChanges If you just want a checklist to follow, you can go straight to https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist If you can't run the entire testsuite for some reason (it can be difficult on Windows), please at least run `contrib/check-code.py` on any files you've modified and run `python contrib/check-commit` on any commits you've made (for example, `python contrib/check-commit 273ce12ad8f1` will report some style violations on a very old commit).
