title: unable to find template, after generating bundle
body: <p>ok this might be a very strange thing.
  it's not the first time I work a symfony project but:</p>
  
  <p>I used the symfony generate:bundle command and after that I created a bundle. Lets call it "CrimeBundle".</p>
  
  <p>I saw it made a folder inside the src/</p>
  
  <p>It also made automatically a DefaultController and an index.html.twig file.</p>
  
  <p>Now whenever I use:</p>
  
  <pre><code>return $this-&gt;render('CrimeBundle:Default:index.html.twig');
  </code></pre>
  
  <p>it doesn't work: I get the error:</p>
  
  <blockquote>
    <p>Unable to find template "CrimeBundle:Default:index.html.twig" (looked into: /Users/admin/sites/solve/app/Resources/views, /Users/admin/sites/solve/vendor/symfony/symfony/src/Symfony/Bridge/Twig/Resources/views/Form).</p>
  </blockquote>
  
  <p>however it works whenever I use the namespaced twig path like:</p>
  
  <pre><code>return $this-&gt;render('@Crime/Default/index.html.twig');
  </code></pre>
  
  <p>I like the first option, because on my other projects I use it too. None of them are the same version, currently I use: 3.4.1
  Again the file is there, because it works with namespaced twig paths.</p>
  
  <p>I can't understand why <code>return $this-&gt;render('CrimeBundle:Default:index.html.twig');</code> wouldn't work as symfony generated this code.</p>
