Testing ActiveRecord::Cte

1. bundle

2. rails db:seed to create 4 posts, 3 of which have comments_count OR tags_count of more than 0.

3. In rails console,

   Post.where.not(comments_count: ..0).
     or(Post.where.not(tags_count: ..0)).
     count

   correctly returns 3.

4. The example from the documentation,

   Post.with(
     posts_with_comments: Post.where("comments_count > ?", 0),
     posts_with_tags: Post.where("tags_count > ?", 0)
   ).
   count

   incorrectly returns 4.
