    playsink: Only remove the complete text chain if the text pad goes away

    If the text pads does not go away we just set the overlay to silent, which
    allows us to immediately re-enable subs later again. However before this
    change we also released the streamsynchronizer text pads, which deadlocked
    because there was still dataflow going on. Just do this only if we remove
    the complete chain.
