Only one addr: tag can be processed currently, so make
sure it is the one without suffixes to not get odd data.
addr:street is the exception because it uses a different
matching mechanism.
Using partial names turned out to not work well because there are
often similarly named streets next to each other. It also
prevents us from being able to take into account all addr:street:*
tags.
This change gets all the full term tokens for the addr:street tags
from the DB. As they are used for matching only, we can assume that
the term must already be there or there will be no match. This
avoid creating unused full name tags.
