Unify the initial audio and video settings with and without local media

When "startWithoutLocalMedia" is called there is never audio nor video
(otherwise "startLocalMedia" would have been called instead), so there
is no need to call "isAudioEnabled" nor "isVideoEnabled". Moreover,
"initAudioVideoSettings" performs the same setup as the custom handling
in "startWithoutLocalMedia", so that custom handling can be replaced by
a call to "initAudioVideoSettings".
