title: SonataUserBundle error while getting users list
body: <p>I have installed a SonataAdminBundle, a SonataUserBundle, FOSUserBundle and my own bundle, that extends FOSUserBundle.</p>
  
  <p>mysite/admin/dashboard looks OK, but when I try to get a users list (mysite/admin/sonata/user/user/list) I get this error:</p>
  
  <blockquote>
    <p>Class Application\Sonata\UserBundle\Entity\User does not exist</p>
  </blockquote>
  
  <p>Why? What I have to do?</p>
  
  <p><strong>UPD:</strong></p>
  
  <p>Okay, now I figured out that problem, but now I have another one.</p>
  
  <blockquote>
    <p>No route found for "GET /admin/sonata/user/user/list"</p>
  </blockquote>
  
  <p>Why this rout does not exist? Where these routes should be placed and why there are none of them in basic SonataUserBundle installation?</p>
