adr: address suggestions have wrong district

[jbruechert]

Arnimalee 14 is definitely in Berlin (as the marker correctly shows), but is considered part of Potsdam-Mittelmark

Yes, the problem is that we're currently using bounding boxes. If an address has for a specific level only one bounding box overlapping it, we take this as the truth and don't calculate with the exact admin_level area shapes. This is only done if we have multiple bounding boxes overlapping the address. So in this case since Berlin doesn't have level 8 admin_areas, we just use the one from Potsdam-Mittelmark. So fixing this would require us to do the exact check for area overlaps everywhere which will significantly slow down the import. But probably that's the way to go.
