Fix Conflicting migrations detected in Django1.9
<p>I updated <a href="https://github.com/dobarkod/django-dynamic-model" rel="noreferrer">django-dynamic-model</a> repository to support Django 1.9. I got this error:</p>

<pre><code>CommandError: 

Conflicting migrations detected; multiple leaf nodes in the migration
graph: (0001_initial, 0002_auto__add_field_dynamicschemafield_extra in
dynamicmodel).
To fix them run 'python manage.py makemigrations --merge'
</code></pre>

<p>After running <code>python manage.py makemigrations --merge</code>, I got another error:</p>

<pre><code> File "/local/lib/python2.7/sitepackages/django/core/management/__init__.py",

 ValueError: Could not find common ancestor of set([u'0001_initial', u'0002_auto__add_field_dynamicschemafield_extra']). 
</code></pre>

<p>Help me to find the solution.</p>
