playsink: Fix disabling of subtitles if subtitles were used before

In this case the video still goes through the text chain and
subtitles are still going in there, in case subtitles are
enabled again. This makes sure that re-enabling subtitles
happens instantly.

Fixes hanging video when disabling subtitles, caused by an
unliked video pad.
