Crash when renaming a component to same name as a deleted inherited component.

Fatal error "UE_LOG(LogObj, Fatal,TEXT("Renaming an object (%s) on top of an existing object (%s) is not allowed"), *GetFullName(), *ExistingObject->GetFullName());" is hit in UObject::Rename. 

Steps: Start a new blank BP project.

1. Create class Alpha, extend it with child Beta.

1. In Alpha, add a component, call it 'Crash'. Compile, save.

1. In Beta, add a component, call it 'NoCrash'. Compile, save.

1. In Alpha, delete 'Crash'. Do not compile, do not save, do not close window.

1. In Beta tab, (Crash should still be visible) rename 'NoCrash' to 'Crash'.

Notice crash.
