Description The DB Poller orders results by a timestamp (like updated_at, created_at, etc.), but if a join was done between multiple tables that share these timestamps, the order query becomes ambiguous, resulting in a crash. This fix sets the owner column for the timestamp to prevent this.

Fixes #112 (issue)

• Existing tests pass successfully. This is a bit of an edge case with my own project, so probably doesn't warrant a full test around it on Deimos. It's just making the ordering a bit more explicit. The service that uses this logic, Content Sieve, has tests that pass with this fix.

@SeanTCasey looks good but:

• lint is failing
• needs rebase
• can we add a spec where we do this via join?
