Making two tests not imply order on the result sets.

These two tests intermittently fail in the sails-postgres integration tests because they imply an order in the result set that is not guaranteed.

This PR and balderdashy/waterline-sequel#16 will allow all balderdashy/sails-postgres integration tests (222, total) to pass against a clean database. The tests do not properly clean up after themselves and will start failing if you run them against a database a few times.
