in prepare_map() explicitly cancel any hero pathing that was started on a different map.
Waiting for the next call of update_hero_pathfinding() is too late, because a tick of movement will have already happened
Also add more autotests for switching maps when pathfinding, but using doors and with "teleport to map"
