demux: fix dropped subtitle packets with the new stream switching
If the previous subtitle packet is too far back, and the refresh seek won't pick it up, and the packet never comes again. As a consequence, the refresh mode was never stopped on the subtitle stream, which caused all packets to be discarded. Fix by assuming the file position is monotonically increasing; then it will resume even if a packet _after_ the intended resume point is returned. This introduces a new requirement on how the demuxer behaves. (I'm not sure if mp4 actually satisfies this requirement in all cases.) Fixes a regression introduced by commit f9f2e1cc.
