SpatialRuleLookupArray.lookupRule throws exception

if exact == true and isBorderTile then the empty rule container passes this if clause and we throw an exception for rule.getBorders() here

Is there a return SpatialRule.EMPTY; missing in the mentioned if clause?

(and it looks like we miss a setBorders call in GraphHopperModule.createGraphHopper -> createSpatialRule. I’ll have to add an integration test after this both fixed)

How would we write an IT for this? The only option I can see is to import a border region and try to route between the regions.

I also added a test for this case.
