Oops, I overlooked that during my cleanup. I added the `dirty = true` option because the Redis adapter does not store the primaryKey explicit as a field, only in the reference-key (which fails a test as `user.id.should.equal id`). I then only worked on the mysql adapter (which clearly does store the primaryKey as a field), so to keep the code "clean" I commented this line. It may come in handy when working again on the Redis adapter, although I doubt it if this is the best method. (It seems to me the best method is to retrieve the value for the primaryKey field from the reference-key of the record).
