Subject: [PATCH] Update PaperLibreLogin.java

Fix when player registers for the first time, he will get tp to the spawnLocation of the default world in the server.properties, every other login, he gets tp to the normal lastLocation he was before, small problem is that the first login tp he is always looking east because i cant get the yaw from the worlds it's always returning 0
