[#4326](https://github.com/CleverRaven/Cataclysm-DDA/pull/4326)

Fixes vehicle teleportation and item/map dupe when we change overmap.

Near the map border, the game was cloning the current submap to a new location when it shouldn’t.

This caused the vehicle to be moved (player “teleports” out), and all items + terrain to be duped.
