Avoid playing newly published audio tracks when deafened (#4040)

Release Notes:

- Fixed a bug where the 'deafen' button would only apply to audio from
the call's current participants, but not any participants who joined
after the button was pressed.
- Fixed a bug where after being granted write access to a channel, the
microphone icon appeared non-muted, even though audio was not shared.
