I have consumer "integration_test_consumer_support" registered to pulp. It has 1 module enabled. When I try to delete all modulemd profiles belonging to this consumer, it simple gets ignored.

1. before profile delete
$ curl -k -u admin:admin https://localhost/pulp/api/v2/consumers/integration_test_consumer_support/profiles/
[{"profile": [{"context": "deadbeef", "version": "20180730223407", "arch": "noarch", "name": "kangaroo", "stream": "0"}], "_href": "/pulp/api/v2/consumers/integration_test_consumer_support/profiles/modulemd/", "_ns": "consumer_unit_profiles", "profile_hash": "f69375f21b302f40025ff8a2128004e81436407554972029cbfbe445d0a2b563", "consumer_id": "integration_test_consumer_support", "content_type": "modulemd", "_id": {"$oid": "5cab7b49db284e2341a2c0ac"}, "id": "5cab7b49db284e2341a2c0ac"}]

1. Delete profile
curl -X "DELETE" -k -u admin:admin https://localhost/pulp/api/v2/consumers/integration_test_consumer_support/profiles/modulemd/ 

1. after profile delete
curl -k -u admin:admin https://localhost/pulp/api/v2/consumers/integration_test_consumer_support/profiles/
