Verify that abort(), abort(undefined) and abort('string') all work as expected, when called on a writer. The reason must be reflected in rejections received from the object.

setCodecPreferences
- Setting codecs to an empty sequence resets codec preferences to any
default value.
- The codecs sequence passed into setCodecPreferences can only contain
codecs that are returned by RTCRtpSender.getCapabilities(kind) or
RTCRtpReceiver.getCapabilities(kind), where kind is the kind of the
RTCRtpTransceiver on which the method is called. Additionally, the
RTCRtpCodecParameters dictionary members cannot be modified. If
codecs does not fulfill these requirements, the user agent MUST throw
an InvalidAccessError.
