Title: Ensure jobs are submitted, oldest workflow first

In Oracle we don't have guarantee of strictly increasing
indexes for the workflows and the JobSubmitter relies
on this to order the workflows and submit older workflows first.
Change the sort to use the timestamp in the last_update column
from the subscriptions.
