Use job id from JobEventDetails to create CupsPrintJobs.

By using job id from JobEventDetails, we can avoid querying CUPS to
display the initial notification and we don't have to guess if we've
identified the correct job.  This wasn't done originally, because job id
was not present in JobEventDetails.

Additionally, add some rate limiting for queries and check for jobs which
we lose track of.

Speculatively, this fixes 682853 as cupsd can become overwhelmed and stop responding to queries.

Report print jobs that are cancelled by CUPS as errors.

If a print job encounters a problem, it can sometimes be cancelled by
CUPS or the printer.  We will now notify the user of an error in this
situation.  If a user cancels a print job, the behavior remains the same.
