Due to what seems to be a bug in ActiveRecord, the distinct: true option is not recognized on counts with string column names. This commit fixes that by moving the DISTINCT into the count string. For robustness, the integration spec for IncomingLinksReport was rewritten to be an actual integration spec, running the actual interface on actual fake data.
