[mediacapture-streams-tests] Fixing comments and indentation, prefixing MediaStream also in audio.html. (#1072)

This is some more errors I found when working to get these running for Chrome layout tests in continuous integration here.

I'm assuming here that wrapping parameters should indent 4 spaces and functions indent 2 spaces after opening brace.
