Alt Drag duplicate no longer calls FEditorModeTools::ActorsDuplicatedNotify

1. Create a Mode which does some custom handling in ActorsDuplicatedNotify (like print some message to the log)
2. Select some actors in the level viewport
3. Alt + drag to duplicate

-> The code in actors duplicated notify will not run, and no breakpoint in FEditorModeTools::ActorsDuplicatedNotify is hit

Expected: The FEditorModeTools::ActorsDuplicatedNotify breakpoint should be hit, or you should see the custom handling from the mode happen.
