Fix change detection when cache is cleared
check_cache_limits() clears the image list. If all subtitles disappear
right in the frame the cache has been cleared, ass_detect_change() will
see two empty image lists (old - not empty, but cleared, new - empty),
and signal to the application that there was no change. As result,
media players which rely on the change detection will keep displaying
the last subtitle until the next subtitle event.
This bug was found by uau and has been reported on IRC in February.
