Fix lastGameType not being updated if game type was demo or save (fixes a crash)
Previously, if you first played a normal game, then a demo, the “play again” button
would appear, but clicking it would only crash HW. This fix will remove this button
after a demo or save, because the frontend doesn't know how to restart demos or saves
yet.
