Bug 20514: Use streetnumber when searching for patrons by address

Bug 20514: Use streetnumber when searching for patrons by address

The streetnumber field was ignored from the search.

Test plan:
Create a patron with streetnumber="12", address="rue des cerisiers"
Search for patrons using the search field "street address"
using: 12 rue des cerisiers
=> Without this patch the patron will not be returned
=> With this patch applied it will!
