Generators on AudioSources that are marked as finished still report isPlaying=true

Steps to reproduce:

1. Make a generator with finite length
2. attach to audiosource
3. Playit

Actual results: audiosource still reports isplaying = true after this length has passed, the generator is also still alive in the DTM

Expected results: audiosource still reports isplaying = false after this length has passed, the generator is removed in the DTM
