front: Allow cheats to be used even if resuming.

I don't know all the ramifications of using cheats, then loading an
auto-save... but the main issue I'm concerned with is when the user
started a game with cheats, then presses home, then resumes the game.
Before this commit, the emulator would shutdown, then startup *without*
cheats, then load the auto-save.  After this commit, the emulator will
shutdown, then startup *with* cheats, then load the auto-save.  I'm not
sure if this will cause problems.
