Ghost game on bad code entry

[tannerkrewson]

If you enter the game code of a game that doesn't exist, you will be placed into a weird ghost game lobby. 👻

unfortunately this is the result of the loading screen feature i added, and unfortunately it's not a trivial fix. When the client receives the joinGameRes response after the client either tries to join or create a new game, it always shows the lobby, and hiding the loading screen from the lobby can only show the lobby. Bad design on my part.
