Title: Issue 1264: create unique index for filter_id

Issue 1264: create unique index for filter_id, so no more duplicate filter counts can be created at database-level

I know, data munging in the migration, but it's for the good cause of
ensuring we don't have any duplicates when creating the index.

Will also deal with the schema, if needed and if I figure it out - will update pull req.
