py-django2: updated to 2.2.8

2.2.8:
* CVE-2019-19118: Privilege escalation in the Django admin.
* Fixed a data loss possibility in the admin changelist view when a custom \ 
formset’s prefix contains regular expression special characters, e.g. ‘$’.
* Fixed a regression in Django 2.2.1 that caused a crash when migrating \ 
permissions for proxy models with a multiple database setup if the default entry \ 
was empty.
* Fixed a data loss possibility in the select_for_update(). When using 'self' in \ 
the of argument with multi-table inheritance, a parent model was locked instead \ 
of the queryset’s model
