Title: Expensive len(QuerySet) ops -> use count() and exists() (#1054)

Also cleaned up
* In views.py remove assignment to object field that's not defined
in the model, which means it would never get saved anyway--NO-OP
* Remove propagation in settings.py for database logs, which were
causing duplicate lines per log entry
