TODO
5.1. removeTrack
Stops sending media from sender. The RTCRtpSender will still appear
in getSenders. Doing so will cause future calls to createOffer to
mark the media description for the corresponding transceiver as
recvonly or inactive, as defined in [JSEP] (section 5.2.2.).
When the other peer stops sending a track in this manner, an ended
event is fired at the MediaStreamTrack object.
6. If sender is not in senders (which indicates that it was removed
due to setting an RTCSessionDescription of type "rollback"),
then abort these steps.
12. Update the negotiation-needed flag for connection.
