Fixes: MSceneManagerPrivate::updateSceneWindowRootElement reparenting effect binder

RevBy: Marcin Miklas, Daniel d'Andrada
Details: if a effect binder is present, it should be the one being
reparented instead of the scene window. Otherwise the scene window will be
in the new root element while its binder and layer effect will remain in the
old one.
