title: Django 1.7 - "No migrations to apply" when run migrate after makemigrations
body: <p>I use Django1.7 with Mezzanine. I create simple profile (according to Mezzanine documentation) stored in separate app "profiles":</p>
  
  <pre><code>class RoadmapProfile(models.Model):
      user = models.OneToOneField("auth.User")
      fullname = models.CharField(max_length=100, verbose_name="Full name")
  </code></pre>
  
  <p>Creation of migrations returns:</p>
  
  <pre><code>  Migrations for 'profiles':
        0001_initial.py:
          - Create model RoadmapProfile
  </code></pre>
  
  <p>When I run "migrate profiles":</p>
  
  <pre><code>Operations to perform:
    Apply all migrations: profiles
  Running migrations:
    No migrations to apply.
  </code></pre>
  
  <p>The issue is, when I try to open any page related to mezzanine.accounts (for example update account), it crashes with:</p>
  
  <pre><code>OperationalError at /accounts/update/
  
  no such column: profiles_roadmapprofile.fullname
  </code></pre>
  
  <p>What I have done wrong?</p>
