test(django): Drop middleware_spans parametrize from test_active_thread_id

The arm only toggled creation of middleware spans, which this test never
inspects: the streaming path skips non-segment spans, and the static path
looks at profile and transaction items. Both DjangoIntegration(middleware_spans=)
settings remain covered by the dedicated middleware-span tests.
