Fix multiple track types not working simultaneously
Bug was caused by the drives_on table of every train and advtrains.all_tracktypes sharing the same reference, which caused advtrains.all_tracktypes to become the intersection of all train drives_on's in the world. However, this did become empty, causing nothing to work anymore.
