deskutils/py-paperless: Switch to Django 2.2
- Assign the port to Django 2.2 as Django 2.1 has reached its End-of-Life on 2nd December 2019.
- Also switch www/py-dj21-djangoql to Django 2.2, remove the expiration date and rename it to www/py-dj22-djangoql accordingly.
Do the same for www/py-dj21-django-extensions [1] as both ports are required by its only consumer deskutils/py-paperless and were originally created for this purpose.
- Bump PORTREVISION due change of the dependencies.
