WebContentsDestroyed

Destroys MediaSessionControllersManager when the web contents is
destroyed to avoid a crash. At the moment when WebContentsImpl
is destroyed it ends up calling GetMediaSessionInfoSync which
calls the destroyed WebContentsImpl. This destroys the media
session controllers before they can do that.
