localrepo: prevent executable-bit only changes from being lost on amend

If you have just executable-bit change and amend it twice it will vanish:

 * After the first amend the commit will have the proper executable bit set
   in manifest but it won't have the the file on the list of files in
   changelog.

 * The second amend will read the wrong list of files from changelog and it
   will copy the manifest entry from parent for this file.

 * Voila! The change is lost.

This change repairs the bug in localrepo causing this and adds a test for it.
