Rick Eyre 7b90a3a973 Bug 905320 - Fix TextTrack classes to utilize cycle collection correctly. r=khuey
We were incorrectly using the wrapper cache cycle collection macros when that
functionality was already implemented by the base classes. Therefore, we
should instead use the inherited version of the cycle collection macros.
