[FIXED] [TM2] Official race and up button bug at start

[icywheels]

Often when I start an official race I hold the up button, probably like most people, and the car does not move after the race starts.

Pressing the up button repeatedly and then holding before green is a workaround.

Still that assumes one remembers something that is about 35-50% of the time.

Appears to be caused by the key bindings. Having the player controls as the only bound controls to specific keys fixes the problem (or a specific binding perhaps).
