Fix logging into a server with Fabric Networking API (#1995) 

* Fix logging into a server with Fabric Networking API

Turns out we prevented the response to LoginPluginRequestPacket. Fabric API 0.28 and later will not let a client join without this response.

* Switch back to Jitpack just for Protocol to prevent weird errors

* Re-add sub protocol check

* Simplify check
