title: Phalconphp cookie getValue return null
body: <p>I need to store information into cookies, Phalcon sets the cookie correctly, but it will not return it, for example: </p>
  
  <pre><code>if(!$this-&gt;cookies-&gt;has('t')){
          $this-&gt;cookies-&gt;set('t', 'test', (10*(365*(24*(60*60))))+time(), '/', null, '*');
  }
  $c = $this-&gt;cookies-&gt;get('t');//when i dump this i can see cookie value as protected value
  $c-&gt;getValue(); // but here i got null
  </code></pre>
  
  <p>As i decribe in comments in example, i got null when i call getValue, but why when i can see the value in dump ?</p>
