Fix order of binding result when using zeroJankProxy

When a new client gets bound to IME, the order of bind events are out of
order: MSG_BIND arrives before MSG_START_INPUT_RESULT (with
InputBindResult.result SUCCESS_WAITING_IME_SESSION). The order needs to
be flipped so that sequence check doesn't mismatch in MSG_BIND.
