Don't fetch comments and downtimes twice in an object's detail view

The controller counts comments and downtimes on the object, which will automatically fetch comments and downtimes.
After that came a call to MonitoredObject::populate() which again fetched comments and downtimes.
Now the object is populated before counting comments and dowtimes.
