Relayout only if the actor is on Scene

We're already checking whether the actor is on scene in RelayoutController::Relayout() before it is added to the mRelayoutStack.
But there is a case that the actor is removed from the scene in the previous OnRelayout.
So check whether the actor is on scene again.
