test_DELETE_x_container_headers_with_more_container_replicas() would sometimes fail, and it's because a test helper method was defaulting to sorting the captured headers by X-Container-Partition. Well, in tests we use FakeRing, and the partition is always 1, so that sorting didn't buy us much. Now the sorting is done by X-Container-Device, which actually differs meaningfully.
