Update tab_singleplayer.lua 

This fixes the situation where it would give you "builtin/mainmenu/tab_singleplayer.lua:167: attempt to index a nil value" where you have nothing selected (for example, switch to minimal game, delete all your old worlds, and then click the toggle buttons for creative or damage).
