Participant API test fails when using DDM on a site together with internationalized wagtail urls

[Nico-AP]

If you use DDM on a Django site together with wagtail (tested with v4.1) and you have internationalization enabled for your wagtail urls, we recommend to use the prefix_default_language=False for the i18n_patterns:

urlpatterns += i18n_patterns(
    path('', include(wagtail_urls)),
    prefix_default_language=False
)

Not doing this will cause ddm.tests.test_apis.test_participant_deletion_with_regular_login to fail.
In practice, the participant API still seems to work properly despite the test failing, however, unexpected behaviour cannot be ruled out at this point.
