When the ConnectionManager stops a Connection while livekitRoom.connect()
is still pending (which happens on every join, because the local
membership emits twice in quick succession and the connection set is
recomputed), livekit-client rejects the pending connect with "Client
initiated disconnect". Connection.start() then treated that as a failure:
it pushed an UnknownCallError into the state of a connection that was
already stopped and rethrew, and since start() is fire-and-forget the
throw surfaced as
Unhandled promise rejection: Error: Failed to connect to Livekit server
in every rageshake, right after a "livekitRoom.connect FAILED ... Client
initiated disconnect" line. Nothing was actually wrong: the replacement
connection connects fine a moment later.
Mark the connection as stopped before disconnecting, and have start()
return quietly when the rejection is the abort we asked for.
