Fix remaining audio speedup/slowdown bug 

Fixes #1057.

Based on Ethan's hunch, I simply removed the format comparison that
decides whether to halt and restart, or reuse the voice. Voices are
now always restarted when playing a new track.

This also simplifies the code somewhat: `MusicTrack::musicVoiceFormat`
was now no longer used, and an `if (!IsHalted())` was no longer
necessary because `Halt()` already does that. So those are now removed
as well.
