Fixing CAY-2379 by focusing the ObjEntity after the undo RemoveAttributeUndoableEdit action

• Divided and set public access to viewCounterpartEntity method in DbEntityCounterpartAction to be able to switch to the ObjEntity from RemoveAttributeUndoableEdit class.
• Added focusObjEntity method to RemoveAttributeUndoableEdit class
• Invoking focusObjEntity method inside undo method, in the section doing the attribute restitution for ObjEntity type

Hi @emecas
Thank you for bug report and especially for this PR.
Have you tried to handle focus directly in RemoveAttributeUndoableEdit class instead of CayenneUndoManager? It should be clearer in my opinion.

Hi, @stariy95

My pleasure :), thanks for your feedback. Actually it was my first attempt, but when i started playing around I observed additional bugs that pushed me to handle the focus on CayenneUndoManager, including an Exception dialog in the modeler that I have not been able to reproduce yet. I will try fix it directly in RemoveAttributeUndoableEdit level and then will back to you asap.

I'll open another issue for documenting and fixing the additional bug.
