Fix issues with WebRTC

[icidasset]

For some reason it doesn't work at all on Safari.
It gives an error that WebRTC is not supported, even though it is.

I looked at various apps that use https://github.com/libp2p/js-libp2p-webrtc-star as well,
and it doesn't look like there is any special setup neccessary for Safari.

Examples:

• https://github.com/ipfs/js-ipfs/tree/master/examples/exchange-files-in-browser

No clue what's going on 🤷

That said, it looks like a better implementation is underway. About the *-star libraries:

These were never designed to be long term solutions, in fact, they were designed to be quick tools for demos. They have design flaws and worse, they end up re-implementing a lot of what libp2p already does (connection authentication, peer discovery, circuit-relay and rendezvous)

More notes:

• https://github.com/libp2p/js-libp2p-websocket-star is no longer supported in js-ipfs
• https://github.com/libp2p/js-libp2p-rendezvous is a replacement for all of this and will be built into libp2p

UPDATE:
Works for the most part with the circuit relay setup.
Still some issues with Safari.
Does not work at all on iOS Firefox and iOS Chrome, see ipfs/js-ipfs-utils#50 for more info.

Looks like it's fixed 🥳
