(v3) need test case for adopting an unmanaged class when an incoming package takes ownership of the class

[dalehenrich]

The class RwGsClassUnmanagedVersioningSymbolDictPatchV2 was created to handle this case and it is not correctly handled during the load.

Working on Rowan4GsDevKit, I have an unmanaged class that exists in the system, but needs to be adopted first and that should be done during RwGsPatchSet_V2>>updateSymbolAssociations which is called BEFORE RwGsPatchSet_V2>>updateClassProperties, however, #installNewClassVersionInSystem is skipped because the class exists in RwGsPatchSet_V2>>movedClassesSymbolList ... it's just that the class is not packaged...

Basic test is passing, but we need more extensive tests cases:

• [ ] create a new class version during load ...
• [ ] add subclasses?
