py-django2: updated to 2.2.19

Django 2.2.19 fixes a security issue in 2.2.18.

CVE-2021-23336: Web cache poisoning via django.utils.http.limited_parse_qsl()

Django contains a copy of urllib.parse.parse_qsl() which was added to backport \ 
some security fixes. A further security fix has been issued recently such that \ 
parse_qsl() no longer allows using ; as a query parameter separator by default. \ 
Django now includes this fix. See bpo-42967 for further details.
