  fix terrain cache not handling terrains not on the map.

previously it functions like underlying_mvt_terrain would only work for mixed locations that are present on the map. This made wesnoth.unit_movement_cost and similar functions return wrong values for those terrains. Even worse, the movetype would cache the 'bad' result leading to bugs such as #2571

fixes #2571
