title: Laravel Voyager: deleting all default bread for tables
body: <p>When I installed voyager, I cleaned up all the default BREADs such as users and roles to just begin my work from scratch and then when I tried to go roles tab on the dashboard I got an error:</p>
  
  <blockquote>
    <p>( <strong>ErrorException</strong>: Trying to get property of non-object )</p>
  </blockquote>
  
  <p>and also the <strong>Menu Builder</strong> in the provided dropdown box <strong>tools</strong> that comes with Voyager gives an error </p>
  
  <blockquote>
    <p><strong>NotFoundHttpException</strong></p>
  </blockquote>
  
  <p>when visiting this route:</p>
  
  <blockquote>
    <p><strong><a href="http://localhost:8000/admin/menus" rel="nofollow noreferrer">http://localhost:8000/admin/menus</a></strong></p>
  </blockquote>
  
  <p><strong>Is it happening because I have deleted a BREAD that I should not have deleted.</strong> ?</p>
