Fixed bug in which you could call the elevator when already was at the call position, moving to the next position and unloading the level the player was currently at.

Now you can only call it when it is not in the players current map (not that its posible in the demo but it will be in the final game).

The issue is that it was already programed to work fine but I forgot to make the final configuration when building the complete elevator, oopsy.
