Error thrown when calling mocked endpoint second time when using file-based response body

[rwwilden]

When you use a setup as follows:

server
  .Given(
      Request
          .Create()....)
  .RespondWith(
      Response
          .Create().....
          .WithBodyFromFile(fileName));

the mocked endpoint can only be called successfully the first time. Second time it will throw an error.

This is caused by the fact that the property BodyData.BodyAsFile is set to null right after the first successful response, causing an ArgumentNullException the second time. This happens in the Response class.
