title: Cakephp 3 hasMany associations a lot of queries
body: <p>I have a Videos.hasMany Comments and Comments.belongsTo Videos</p>
  
  <p>so when i do  </p>
  
  <pre><code>/*Select video by id*/   
   $videos = $this-&gt;Videos
      -&gt;findById($videoId)
      -&gt;hydrate(false)
      -&gt;contain(['Comments']);
  </code></pre>
  
  <p>i end up with 23 select query instead of 2.</p>
  
  <pre><code>SELECT * FROM videos;
  SELECT * FROM comments WHERE video_id IN (1) ;
  SELECT * FROM comments WHERE video_id IN (1) ;
  SELECT * FROM comments WHERE video_id IN (1) ;
  SELECT * FROM comments WHERE video_id IN (1).... ;
  
  is there anyway to execute only 2 queries,Am i doing something wrong ?
  </code></pre>
