AttributeError when running 'makemigrations' on Django 1.8

I found this while doing some initial testing with Django 1.8 using latest code (commit 1376a667d9a2baa0e383024c8dbaee59e924bade) after waiting for issue #105 to be closed.

When running python manage.py makemigrations on an containing an hstore.DictionaryField in schema mode schema I get the following error:

Traceback (most recent call last):

AttributeError: '_Meta' object has no attribute 'model_name'

No changes were made to my model. The virtual field in question has these specs:

{
       'name:' 'my_field',
        'class': 'TextField',
        'kwargs': {'blank': True, }
}

@nemesisdesign @aidanlister This is the only issue I was able to find since your fix for Django 1.8. Everything else seems to be working normally for me.

Others have discussed this same bug here.

Looks like something here: https://github.com/djangonauts/django-hstore/blob/master/django_hstore/virtual.py#L91
