Fix FS#8977. The issue was caused by multiple successive calls to audio_load_track() happening before the corresponding calls to audio_finish_load_track(), resulting in disappearing tracks. I added the track_load_started boolean flag as a means to prevent audio_load_track() from doing anything if a call to audio_finish_load_track is pending.
