End of a request is not traced with async methods

[fedotovalex]

When request tracing is enabled and async request methods are used, only the beginning of the request is traced, not the result. This is probably caused by the premature disposal of the TransportRequestState object here.

Doh, you are absolutely right @fedotovalex this should be fixed asap.

Took some time but we finally got around to fixing this, should make it in the next release. Thanks again for reporting @fedotovalex 👍
