test: Ignore results from django main branch

- there are sometimes breaking changes introducted in django's
  main branch, that other dependencies take time to handle.
  For example: our CI has been broken for almost a month now,
  due to the breaking change in django/django#15797.

  Hence, ignoring the results of the django main branch for now,
  to allow all other patches to be merged.
