title: Django CircularDependencyError on migrations
body: <p>I cloned a git repository with a Django app and opened it on Pycharm and made some changes to it.</p>
  
  <p>Among these changes I did <code>add_to_class</code> on the Group class from django, to add a field named <code>modulo</code>.</p>
  
  <p>I closed this project and cloned the repository again, and made all the initial migrations and all. The problem is, when I try to <code>migrate</code> I get this error</p>
  
  <pre><code>django.db.migrations.exceptions.CircularDependencyError: BOXCFG.0001_initial, auth.0010_remove_group_modulo, auth.0009_group_modulo
  </code></pre>
  
  <p>Seems like the changes I did on the Django native model are still somehow getting in the way of my migrations.</p>
  
  <p>I tried deleting everything, migration history, the table migration field, the folders the database... And I still get this error when trying to make my migrations.</p>
  
  <p>How do I solve this? Where can I clear the Django migrations so that I start all over again without the changes I did in another project?</p>
