Hope we can sort this out, more and more fixes suffer from the wrong testing
failures and nothing new gets integrated.


12996 ClassTest>>#testRenaming leaves dirty package Dummy-Tests-Class behind
12995 CI ClassTest>>#testRenaming is failing

available options:
1. skip test
2. test for nil in RPackageOrganizer>>#systemClassRenamedActionFrom:
�� before
�� rPackage updateDefinedClassNamed: oldName withNewName: newName.
3. review changes for issue 12601
��� (fix RPackageOrganizer>>#systemCategoryRemovedActionFrom: ann, to
��� unregister packages even if there are MCPackages (don't know about the
��� side effects)

best solution would be number 3, but the recent submissions for
issue 12601 are quite complex, so I don't know.
