Important: Job lists break starttime ties by uid 

Description 

The job lists order by starttime through the repository's $defaultOrderings — but starttime is 0 for every job that was never scheduled, so most of a typical list tied and the relative order of the tied records belonged to the database. On PostgreSQL that is not the same list twice. The default orderings now carry uid ascending as a tiebreaker.

Impact 

No visible change is expected: within equal starttime values, uid ascending is the order every supported database returned in practice, it is simply guaranteed now rather than coincidental. Jobs with different starttime values keep their order.
