title: Symfony2 - fos create super admin custom field required
body: <p>I am deploying a SF2.1 project into production.<br>
  I have customized the user model so that certain fields are required.<br>
  So when I try to create my super admin</p>
  
  <pre><code>$ php app/console fos:user:create admin my@mail.com my_pass --super-admin
  </code></pre>
  
  <p>I'm getting</p>
  
  <blockquote>
    <p>[PDOException]<br>
    SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'my_required_field' cannot be null</p>
  </blockquote>
  
  <p>What is the clean way to manage that ?<br>
  I Imagine not manually inserting the user into the table...</p>
