guard against hiding priv->stage when already destroyed during dispose

Before chaining up to gtk in gtk_clutter_embed_dispose we destroy
priv->stage, but gtk will emit a hide signal during it's dispose so we
need to guard against calling clutter_actor_hide (priv->stage) if
the stage has been destroyed.
