hlsdemux: Send a flush-stop when switching pads. Fixes A->A/V sync issue.

Browse source 
This is to ensure that we reset the accumulate segment on the sinks
so if we start with audio only then switch to audio+video, then both
sinks will have the same segments and will be synchronized.

/* FIXME: This is a workaround for a bug in playsink.
* If we're switching from an audio-only or video-only fragment
* to an audio-video segment, the new sink doesn't know about
* the current running time and audio/video will go out of sync.
*
* This should be fixed in playsink by distributing the
* current running time to newly created sinks and is
* fixed in 0.11 with the new segments.
