Nominatim/lib/AddressDetails.php
Sarah Hoffmann 411f361fcb traverse address list backwards when computing admin levels
By starting with the lowest address level, when collecting
administrative boundaries by level, there is a better chance
to actually get the boundary when the capital of the
administrative boundary is tagged with the level of the
boundary as well.

This is just a heuristics adaption to make the best out of
the imprecise admin_level definition for place nodes.

Fixes #1261.
