Fix rare race condition with transitioning

If the player unexpectedly disconnects after ServerConnectEvent is
fired, but before the connection transitions to the new player, Velocity
would throw an exception thinking the connection was not present. This
is the correct behavior, but the behavior is very surprising. Instead we
will double-check to ensure the connection has not been lost before we
continue with transitioning to the new server.
