Title: Respond with an ACK response to a CON block-wise request.

The server returns a NON response (instead of ACK) to a block-wise CON request.

To reproduce, run cf-plugtest-client against cf-plugtest-server. Test cases CB01 and CB02 fail.
The client tries to retransmit the request even after receiving the full response but the server drops it.
After DEFAULT_OVERALL_TIMEOUT the `Message.responseTimeout()` is called.

After applying this small change CB01 and CB02 test cases pass and the `Message.responseTimeout()` is not called.
