SUS-3263 | FavoriteWikisModel - use rollup_wiki_user_events instead of events_local_users

[macbre]

https://wikia-inc.atlassian.net/browse/SUS-3263

Let's use rollup_wiki_user_events from Data Engineering instead of events_local_users. We want to get rid of all cross-wiki use cases of the latter table.

The functional difference will be that only the activity from the recent 90 days will be taken into account (instead of since The Beginning Of The Known Universe).

New query

mysql@geo-db-dataware-slave.query.consul[statsdb]>select wiki_id, sum(edits + creates) as edits from rollup_wiki_user_events where period_id = 2 and user_id = 119245 and time_id >= NOW() - INTERVAL 90 DAY group by wiki_id order by edits desc;

-- temporary and filesort on 23 rows is not a big deal
