Add order-by-ID to PhabricatorWorkerTriggerQuery

Summary:
Ref T6881. By design, the EXECUTION order only selects tasks which have been scheduled (since it performs a JOIN). This is inconsistent with other queries and problematic for withID/withPHID queries which may want to select an unscheduled task.

Switch to standard ID ordering by default.

Test Plan:
- Instances console now finds unscheduled triggers.
- Verified that all existing queries specify an explicit order.
