29128	makemigrations raises AppRegistryNotReady instead of ImproperlyConfigured in Django 2.0	Jaye Doepke	ChillarAnand	"In Django 2.0 with settings that should raise `django.exceptions.ImproperlyConfigured`, running `manage.py makemigrations` will raise `django.exceptions.AppRegistryNotReady` instead. This does not occur in Django 1.11.

**Steps to Reproduce:**

$ django-admin startproject example_project .
$ echo 'SECRET_KEY = None' >> example_project/settings.py
$ ./manage.py makemigrations
