  ai_helper.get_closest_location: bug fix for border hexes

If a unit is passed as the last argument to this function, the returned hex is supposed to be passable for that unit. Hexes on the map border need to be excluded in this case.

This specifically also fixes a bug in the Messenger Escort Micro AI. Previously, waypoints right at the map border could sometimes lead to the AI showing an on-screen error message and becoming inactive.
