Get Editor Actor from PIE & SIE Actor

See EditorUtilities::GetEditorWorldCounterpartActor

Danger

This doesn’t work if using level instances. The internal iterator only finds correct editor actor if the actor is in the persistent level

Ugly fix that works with level instances (full code for a complete version of GetEditorWorldCounterpartActor)

UWorld* EditorWorld = GEditor->EditorWorld;
for (auto LevelIt(EditorWorld->GetLevelIterator()); LevelIt; ++LevelIt)  
{
	if (const ULevel* Level = *LevelIt)
	{
		UWorld* World = CastChecked<UWorld>(Level->GetOuter());
		for (TActorIterator<ABPGCableManager> It(World); It; ++It)  
		{
			if (It->GetActorLabel().Equals(this->GetActorLabel()))
			{ 
				It->SetSavedDataFromPIE(SavedBodyInstances);
				return;
			}
		}
	}
}
