Fixed output of http status in access log 

There was a following case:
Client sent a request. Server received only a part of request and had already known that request cannot be processed (either bad request, or some internal error or something else). Server sent some response for Client. Client got response, interrupted sending of request and shutdowned socket. Thevoid tried to recive the rest of request, got an error of reading from the closed socket, decided that Client went away before request had processed and printed 499 http status.

The behaviour for that case was changed: If Client gets whole response from Server, the resposne's http status will be printed in access log instead of 499.
