Fix StartGame NullReferenceException in multiplayer

Browse Source 
Remove MainMenuMode.StartGame() reflection call that expected
"Choose Your Map" screen state. Clients never see this screen
in multiplayer, causing null references. Now transitions directly
to playing mode like save loading does.

Fixes: NullReferenceException at MainMenuMode.StartGame()
