Subject: [PATCH] CB-10502 Fix camera plugin exception in Chrome when click
 capture.

The MediaStream.stop() method has been deprecated as of Chrome 47. We were using it, and it was generating an exception.

If stop() method is not found, instead stop each individual track (the new way of doing it).
