Re: [media-source-tests] Checks MediaSource.activeSourceBuffers and changes to track state (#3182)

Investigating per https://github.com/w3c/web-platform-tests/pull/3182#issuecomment-240587688, the test looks right, Chrome needs fixing (only HTMLMediaElement.{audio,video}Tracks lists get the 'change' events, not SourceBuffer.{audio,video}Tracks, when selected/enabled track state changes). I've filed https://crbug.com/639151 to get Chrome compliant with 'change' events on SourceBuffer.{audio,video}Tracks.

I'll merge this PR with additional commit(s) that address my comments shortly.
