https://de.wikipedia.beta.wmflabs.org/wiki/Spezial:Aktive_Benutzer shows all the temp users from the last 30 days.

Would not expect them counted as active as that not the case when ips doing the edits

One fix should fix also {{NUMBEROFACTIVEUSERS}} and the count on Special:Statistics

Code is in RecentChangesUpdateJob::updateActiveUsers, needs to call isTemp on each actor_name
