`azure_devops_rust_api::test::results::Client::update()` stalls indefinitely or fails to deserialize.

Sorry, this isn't a very pretty report, I sadly don't have the time to investigate this further right now.

But running this request with a body with an state enum value that doesn't exist results in this call not returning at all. Additionally, the lastUpdatedBy field in the response will contain null values and this breaks some deserialization.

On your second point, I see that the example response in the REST API docs shows lastUpdatedBy with an id of null:

{
  "count": 2,
  "value": [
    {
      "id": 100000,
      "project": {},
      "testRun": {},
      "lastUpdatedBy": {
        "id": null
      },
      "url": ""
    },
    {
      "id": 100001,
      "project": {},
      "testRun": {},
      "lastUpdatedBy": {
        "id": null
      },
      "url": ""
    }
  ]
}

Currently the code expects id to always defined. I'll fix this to make it an Option.
