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

Fyi the official way to read (non-zero) RTP stats is to wait for RTP, [like this](https://jsfiddle.net/jib1/y0k2p3of/):
  pc1.addTrack((await gUM({video:true})).getTracks()[0]);
  const {track} = await new Promise(r => pc2.ontrack = r);
  await new Promise(r => track.onunmute = r);
  const stats = await pc1.getStats();
  console.log(`${[...stats.values()].filter(({type}) => type == "outbound-rtp").length} outbound-rtp`);
But note that due to [crbug 1295295](https://crbug.com/1295295) this would still return stats early in Chrome. 🤷🏼‍♂️
