In this case, shared vision would remove units which we lost contact with 
because of shared vision(We cannot see the tile). And remove_allied_visibility 
would remove units in transports(and cities) on tiles which we could still see. 
If alliance is canceled first remove_allied_visibility would remove units in 
transports. And remove_shared_vision on tiles which we cannot see.
