In the situation you were in, I would first focus on getting myself safe and grabbing the reins and my stirrups, but I think I would have read the situation and done this earlier before the bolt happened, or it would have been in progress.
Once you are secure, try to make it stop. Like pumping the brakes in a car, on and off with the reins, and steering to avoid dangerous situations. As you were in an indoor, there is not any place for the horse to go, but if you were out, I would have see sawed the face until the horse stopped. Not ideal, but a bolt it not ideal either.
Others might disagree with this, but this is what I would have done, and I would not attempt a one rein stop at high speed.
