Our spec. says we return nulls for started and status if we don't find
a job matching the host spec.

The way this works right now is that we look up the nonexistent
entries in $refs->[0].  This is not really brilliant and is going to
be troublesome as we continue to refactor.

Provide these values explicitly.  No functional change.
