Setup support for all login methods via Streamlabs

To sign in with Streamlabs, you can user multiple providers. Many people use Streamlabs with other providers other than Twitch. Need to account for the following:

- [ ] Streamlabs
- [ ] Youtube
- [ ] Mixer
- [ ] Facebook

this is also what is causing the `UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'id' of undefined` error in Heroku.
