The evidence of the absence of 'frameError' listener is the blame is that if you add such a listener to the http2Session in the server side in the test, client can get a response.
This PR ensures 'onFrameError' in JS, which takes care of cleanup get called even if no user registered 'frameError' listener.

// Called by the native layer when an error has occurred sending a
// frame. This should be exceedingly rare.
function onFrameError(id, type, code) {
const session = this[kOwner];
if (session.destroyed)
return;
debugSessionObj(session, 'error sending frame type %d on stream %d, code: %d',
type, id, code);
const emitter = session[kState].streams.get(id) || session;
emitter[kUpdateTimer]();
emitter.emit('frameError', type, code, id);
session[kState].streams.get(id).close(code);
session.close();
}

I was afraid it would revert the memory leak fix I did a while ago. But, the since the CI is green I think we are good. LGTM.

Why? I meant I didn't approve this PR before because I was waiting for the CI to run to guarantee this won't bring back the memory leak issue.
