Our Ktor network implementation seems to have issues on macOS.

This can be reproduced 100% using our KtorNetworkTransportTest.requestSuccessful(). This test that we successfully can use all HTTP methods: GET, POST, PATCH, PUT, DELETE

Observations:

• The order matter. With the above order, PUT and DELETE starts to fail with ClientRequestException
• If I change the order and test PUT first, it works.
• When creating the Ktor HttpClient for each request it works.

Hypothesis:

• It is either related to some state inside Ktor not being correctly cleaned up. Either because we are misusing the API somehow, or because of a bug in Ktor. Unclear how to investigate this.
• It is related to the HttpClient being frozen. We should be able to verify this by using a single-threaded dispatcher and create the client inside that the first time.

Work-around:

• Create a new HttpClient for each HttpRequest.
