Fix indexing problem with mac devices (#4676) 

* Fix indexing problem with mac devices

This resulted in the wrong device being selected.

Also, fix a shutdown crash where recording was not being stopped, hence the recording
thread was still running on shutdown and crashed because it lost access to resources.

Fix an issue with p2p calls where they're coming up muted even though the button indicates
they are unmuted.

* Always refresh device list on notification of device changes

Even when the selected device doesn't change, we need to
re-deploy it as it might have had characteristics (sampling rate, etc.) changed.

Also, we need to redeploy when the Default device has changed
