Error in custom migration 0009

The custom migration 0009 in line 30:

https://github.com/Wtower/django-ninecms/blob/devel/ninecms/migrations/0009_auto_20150924_1456.py#L30

Does not sufficiently check if the media/ninecms folder exists, which rarely happens in a clean migrate. This results in the following traceback:
