Filtering unnecessary urls from affiliation service response

Due to fact that affiliation service receives hash of the urls, and not
the urls themselves it could return affiliations that were not requested.

Now the algorithm, that parses affiliation service response, actually
checks, if these affiliations were requested or not and the unnecessary
affiliations are being deleted.
