* Clarify that sdpMid and sdpMLineIndex are not required in `m.call.candidates`
MSC2746, merged in v1.17,
introduced the end-of-candidates candidate,
where only the `candidate` property is set to an empty string.
Besides, the [WebRTC specification](https://www.w3.org/TR/webrtc/)
says that only one of those fields is required in a normal candidate.
