do not return POIs when dropping house number in query

Browse Source 
We've previously added searching through rank 30 in a house
number search to enable searches for house number+name.
This had the unintended side effect that rank 30 objects
are also returned in s search that dropped the house number
from the query. This is wrong because POIs cannot function
as a parent to a house number.

This fix drops all rank 30 objects from the results for a
house number search if they do not match the requested house
number.
