title: $this->set('title', 'Title Name'); not working in CakePHP 3.x
body: <p>Basically in default.ctp I have this for my title:</p>
  
  <pre><code>&lt;title&gt;
    &lt;?= $this-&gt;fetch('title') ?&gt;
  &lt;/title&gt;
  </code></pre>
  
  <p>And inside of the controller I have this line:</p>
  
  <pre><code>$this-&gt;set('title', 'Test-Title');
  </code></pre>
  
  <p>But it does nothing, it still displays controllers name(Jobs, controllers full name os JobsController.ctp)</p>
  
  <p>But if I put this inside of my view file:</p>
  
  <pre><code>$this-&gt;assign('title', 'Test-Title');
  </code></pre>
  
  <p>It changes the title. So what is wrong with $this->set('title', $title) <strong>?</strong></p>
