Android runs out of tracks playing sounds

[chrisgarrity]

Steps to reproduce:

1. Create a project with several longer sounds on a sprite
2. Drag out the individual sound blocks and tap them randomly to start/restart them playing
3. Eventually some of the sounds won't play when the device runs out of tracks.
4. If some of the sounds are playing, each sound will still play if you wait until other sounds finish before tapping, but probably won't play more than one at the same time.

Here's an except of the adb logcat when tapping a sound that won't play.

ScratchJr only allows one instance of a sound to be playing at a time. I'm guessing that when a sound gets restarted the track resource grabbed for the original sound doesn't get released. Since tracks are shared across the whole device it depends on what else is holding on to tracks, but eventually the sound stops playing when the sound block is tapped.
