playsink: Reset ts_offset field when freeing chain

Browse source 
Otherwise we would end up with a bogus ->audiochain->ts_offset field
which would cause segfaults/assertions when trying to modify the
'ts-offset' property in update_av_offset().

Was easy to trigger when using a list of audio+video files mixed with
video-only files in totem.
