CE-1029 Making ImageReview usable

I am aware that this is not the perfect fix, however - it works. The most important thing now is to make ImageReview usable on daily basis and introduce better solutions subsequently.

#### Before:
```sql
explain SELECT pages.page_title_lower, image_review.wiki_id, image_review.page_id, image_review.state, image_review.flags, image_review.priority  FROM (  SELECT image_review.wiki_id, image_review.page_id, image_review.state, image_review.flags, image_review.priority  FROM `image_review`  WHERE state = 0 AND top_200 = false  ORDER BY last_edited desc  LIMIT 24  ) as image_review  LEFT JOIN pages ON (image_review.wiki_id=pages.page_wikia_id) AND (image_review.page_id=pages.page_id);
```
```
