Re: [webrtc-pc] example 13: getReceivers semantics

I agree it doesn't make sense. But signaling track IDs is redundant in the first place, now that we have MIDs. So, from my perspective, this is just legacy baggage we have to deal with, and it doesn't really matter what we do as long as the behavior is predictable.

But then the early media example wouldn't work. The RtpReceiver and track should be available right after `addTransceiver`, so it can immediately be hooked up to a `<video>` tag, before the remote SDP is received.
