The more complicated version is a LOT faster - and was added because
the version in this patch was just way too slow (unusably slow).

I think it's better to also remove the call to db-get-outputs (and
the entry #:outputs) entirely.  I don't think our overview page even
shows the outputs in the first place, so why fetch them?
