package/python-django: security bump to version 3.0.7

Fixes the following security issues:

- CVE-2020-13254: Potential data leakage via malformed memcached keys

  In cases where a memcached backend does not perform key validation,
  passing malformed cache keys could result in a key collision, and
  potential data leakage.  In order to avoid this vulnerability, key
  validation is added to the memcached cache backends.

- CVE-2020-13596: Possible XSS via admin ForeignKeyRawIdWidget

  Query parameters for the admin ForeignKeyRawIdWidget were not properly URL
  encoded, posing an XSS attack vector.  ForeignKeyRawIdWidget now ensures
  query parameters are correctly URL encoded.

For details, see the announcement:
https://docs.djangoproject.com/en/dev/releases/3.0.7/

Additionally, 3.0.5..3.0.7 contains a number of non-security related
bugfixes.
