Use redux for local tracks instead of conference.js (#9920)
Use redux for local tracks instead of conference.js (#9920)

* do not use this.local video

* move tracks initialized flag around

* do not use this.localAudio

* untangle use audio/video stream methods

It should be safe to call setVideoMuteStatus and
setAudioMuteStatus regardless of the prejoin page
visibility state.

* add NO-OP to use track methods and fix crash
in _setLocalAudioVideoStreams on not a promise

* use allSettled
