[webrtc-stats] WPT tests are wrong about when "outbound-rtp" and "inbound-rtp" stats appear (#619)

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

== WPT tests are wrong about when "outbound-rtp" and "inbound-rtp" stats appear ==
The [spec](https://w3c.github.io/webrtc-stats/#the-rtp-statistics-hierarchy) says: _"The lifetime of all RTP [monitored objects](https://w3c.github.io/webrtc-stats/#dfn-monitored-object) starts when the [RTP stream](https://w3c.github.io/webrtc-stats/#dfn-rtp-stream) is first used: When the first RTP packet is sent or received on the [SSRC](https://w3c.github.io/webrtc-stats/#dfn-ssrc) it represents, or when the first RTCP packet is sent or received that refers to the SSRC of the RTP stream."_

TL;DR: no packets no stats.

Yet these WPT tests assume stats appear immediately after negotiation (ahead of `"connected"` even):
