When mic is locked, user is not able to talk so it doesn't make sense
to alert the user about unmuting (mute button is also disabled when mic
is locked).

Closes #12048

Complements #12705

Here's what we do when user activates mic:
1 - When we do something similar to listenonly's joining process
until we find a valid candidate-pair. The information about this
local candidate is store.
2 - We then start a new userAgent, and as soon as browser finds
a candidate with the same local ip address, we leave only this
candidate in the SDP and send this to FreeSWITCH. SDP should
contain only a single candidate.
3 - The rest of signaling process is basically the same.
