LibVideo/PlaybackManager: Don't crash when demuxer seek throws an error

Browse source 
`seek_demuxer_to_most_recent_keyframe()` wasn't correctly returning in
cases where an error was thrown by the demuxer. To avoid this, the
function now returns the error, and the playback state handler must act
on it instead, allowing it to exit the seeking state early.
