Created print jobs should not be persisted until they are queued.

Print jobs in a created state should not be persisted. However,
if a print service sets the tag to a print job that is queued,
we were persisting even print jobs in a created state. This
change adds a simple check while persisting to avoid storing
created print jobs.
