Crash when Undoing GameObject copy after Transform.SetParent(null) call to set World as the parent
Reproduction steps:
Create empty project
1. Import and open the project scene (TestUndoBugCrash.zip)
2. Select the Cube prefab instance inside the "Parent" object
3. Click the button in Game View to duplicate the prefab
4. Observe that the prefab copy is a child of World now
5. Ctrl+z triggering Undo will crash Unity
Expected result: Editor undoes the last action
Actual result: Editor crashes
