Installing releases/1.0 adds unknown package html_email INSTALLED_APPS

What happened?

After Installation (no stripe, no paypal, no sendcloud - all other settings like default) of the head of releases/1.0 (at d05d4be ) initialize_shop_demo crashed with the error

Traceback (most recent call last):

What should've happened instead?

pipenv run ./manage.py initialize_shop_demo should run migrations and install fixtures.

Steps to reproduce

cookiecutter https://github.com/awesto/cookiecutter-django-shop --checkout releases/1.0 # paypal, stripe and sendcloud -> no; other settings default
cd my-shop
# replace select2 line in Pipfile (see #16 )
pipenv install --sequential
pipenv run ./manage.py initialize_shop_demo
