Description of problem:
With the database of this customer imported, the retirement date seems ignored and the scheduler seems to never pick up service retirements. 

Version-Release number of selected component (if applicable):
5.10.0

How reproducible:
only with customer database

Steps to Reproduce:
1.import database provided from customer
2.schedule a service retirement
3.

Actual results:

The object in rails has the correct retirement date, as well as the UI.  It looks like schedueler's never picking them up for some reason.

You can see the MiqScheduleWorker constantly having at least 1 task to do, I'm assuming it's the retirement one that never gets done:
