red: fix renegotiation

If RED is no longer used the send codec needs to be reconfigured.
To test on https://webrtc.github.io/samples/src/content/peerconnection/audio/
run:
  await pc1.setLocalDescription();
  await pc1.setRemoteDescription({type: 'answer', sdp:
        pc1.remoteDescription.sdp.replace('red/48000', 'blue/48000')})
As a result, RED will be turned off and the bitrate will drop.
