title: Django: I get a [relation "auth_group" does not exist] error after syncdb
body: <p>I started a new Django 1.8 project and realized that I missed something (i had done the initial migrations). I dropped the database (postgreSQL) and deleted <code>migration</code> folders from all my apps in order to start from scratch.  </p>
  
  <p>Now, when I 'syncdb' I get this error: </p>
  
  <p><code>django.db.utils.ProgrammingError: relation "auth_group" does not exist</code></p>
  
  <p>and when I <code>makemigrations</code> I get this:</p>
  
  <p><code>No changes detected</code></p>
  
  <p>What am I doing wrong?</p>
