title: Unable to find template in Bundle
body: <p>I am using <code>Symfony 3.4.4</code> and getting Twig_Error_Loader:</p>
  
  <pre><code>Unable to find template "MyBundle:Default:index.html.twig" (looked into: /Users/nemanja/sites/SimfoniAplikacija/app/Resources/views, /Users/nemanja/sites/SimfoniAplikacija/vendor/symfony/symfony/src/Symfony/Bridge/Twig/Resources/views/Form).
  </code></pre>
  
  <p>This is my default controller in MyBundle/Controller</p>
  
  <pre><code>&lt;?php
  
  namespace MyBundle\Controller;
  
  use Symfony\Bundle\FrameworkBundle\Controller\Controller;
  use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
  
  class DefaultController extends Controller
  {
      /**
       * @Route("/my", name="mypage")
       */
      public function indexAction()
      {
          return $this-&gt;render('MyBundle:Default:index.html.twig');
      }
  }
  </code></pre>
  
  <p>And my index file is where it says: <code>MyBundle/Default/index.html.twig</code></p>
  
  <p>I tried to change return <code>$this-&gt;render('MyBundle:Default:index.html.twig');</code>
   to  <code>return $this-&gt;render('MyBundle/Default/index.html.twig');</code>
  But I still get the same error. It can't find index template.</p>
