Ensure there isn't duplication in federated auth

In I9a150ded6c4b556627147d2671be15d6a3794ba5 a comments was made that
we should test /auth/projects and /auth/domains in addition to
/OS-FEDERATION/project and /OS-FEDERATION/domains. This commit
ensures both API behave the same when pruning duplicate projects
and domains.
