[webrtc-stats] Datachannel "transportId" doesn't say which transport (#575)

alvestrand has just created a new issue for https://github.com/w3c/webrtc-stats:

== Datachannel "transportId" doesn't say which transport ==
https://w3c.github.io/webrtc-stats/#dom-rtcdatachannelstats-transportid - says "A stats object reference for the transport used to carry this datachannel."

The datachannel runs on top of an SctpTransport, which runs on top of a DtlsTransport, which runs on top of an ICETransport (the two latter are merged in the stats object model). So "the transport" is ambiguous.

I think the reference should be to the SctpTransport, and the text should say so.
