fix(base/tracks): handle GUM in progress
This commit adds extra actions/Redux state to be able to deal with
the GUM operation being in progress. There will be early local track
stub in the Redux state for any a local track for which GUM has been
called, but not completed yet.
Local track is considered valid only after TRACK_ADDED event when it
will have JitsiLocalTrack instance set.
