Update webrtc stats bridge for modern Chrome/Firefox APIs

Switch to the promise-based getStats, and use the standardized
property names where available, with fallback to handle Chrome,
which hasn't fully switched yet.

The stats now only track the outgoing audio stream, as a way to
indicate quality, since the user can't hear themselves. This
might be revisited later; it would require tracking the stats
separately for incoming vs. outgoing and e.g. returning whichever
is worse.

Send the previously non detected as finished text object before keeping focus on the last created one.
