http: prevent aborted event when already completed

billywhizz · Leko · commit 1980a36dd459 · 2018-03-02T01:07:41.000+09:00
When socket is closed on a response for a request that is being piped to a stream there is a condition where aborted event will be fired to http client when socket is closing and the incomingMessage stream is still set to readable. We need a check for request being complete and to only raise the 'aborted' event on the http client if we have not yet completed reading the response from the server.
