fix(housekeeping): add where clause to check episode_id is not null on reset comments count

            ->select('fediverse_posts.episode_id as episode_id, COUNT(*) as `comments_count`')

            ->join('fediverse_posts as fp', 'fediverse_posts.id = fp.in_reply_to_id')

            ->where('fediverse_posts.in_reply_to_id', null)

            ->where('fediverse_posts.episode_id IS NOT', null)

            ->groupBy('fediverse_posts.episode_id')

            ->getCompiledSelect();
