[BUGFIX?] SaveData using a player 2 controls instead of player1 controls

[gamerbross]

SaveData was using player2 controls because of an incorrect check (assumed playerId 0 is for player1, so always used player2 instead).

Warning

This change will wipe user's controls.
Could be fixed with some kind of migration of the save data, maybe increasing savedata version and moving player2 controls to player1 controls, and emptying player2 controls
