Webtorrent - multiple failures

Multiple webtorrent issues
e.g. on http://localhost:4244/details/commute?mirror=&transport=HTTP&transport=WEBTORRENT
- [x] not loading image - unclear what this means ?
- [x] stats not working
- [x] need to delete stat updater in componentDidUnmount (in AudioVideo.jsx)
- [x] not trying to get from WT see below - fixed, was not passing through change from loadfrommetadata to AI constructor to AF
- [x] Not seeing any kind of fetch in console log
- [ ] archive denying connection - see below
- [ ] fastrak denying connection
- [x] Cors errors getting parts - but this was 503 errors from ingress - requested change from @tracey
- [x] Why is it reading the `.avi` and `.ogv` - should only be getting the .mp4 but might just be head or a few bytes before/after
- [ ] Warning message in console - maybe harmless https://github.com/feross/render-media/issues/73
- [x] href: "magnet:?xs=https%3A%2F%2Fwww-dweb-torrent.dev.archive.org%2Fcommute_archive.torrent&xt=urn:btih:7e849a0f2c0e5f9ea6ab72827e7690406904b010&tr=http%3A%2F%2Fbt1.archive.org%3A6969%2Fannounce&tr=http%3A%2F%2Fbt2.archive.org%3A6969%2Fannounce&tr=wss%3A%2F%2Fdweb.archive.org%3A6969&tr=wss%3A%2F%2Ftracker.btorrent.xyz&tr=wss%3A%2F%2Ftracker.openwebtorrent.com&tr=wss%3A%2F%2Ftracker.fastcast.nz&ws=https%3A%2F%2Farchive.org%2Fdownload%2F/commute.mp4"
