Sarah Hoffmann 8eb85f1340 increase penalty for places without housenumber
Results where the housenumber was dropped are an unlikely result
when they refer to something other than a street. Therefore
increase their result rank so that other matches are tried first
before choosing them as a result.

Improves #2167.
