It is not given, that null values are sorted last in the `order_by("-end_time")`
statement. This did not happens in the tests, but in a productive environment.
See https://docs.djangoproject.com/en/2.2/ref/models/querysets/#order-by for a
`.asc()`/`.desc()` option `nulls_last`. I choose another approach to just
exclude these values.
