[bug][fix]Changeset is not updated when renaming a class

Hi,

As reported on Mantis (http://bugs.impara.de/view.php?id=3415), after
renaming a class, the changeset is not updated to refer to the new
name. Therefore, one virtually lose recorded changes. I first
identified/fixed the bug in
3.9-7021. But, it looks it's still in 7022.

Attached the fix
