amqp.connect calls error callback twice when bad credentials are given

[Froren]

I'm using version 0.4.2 of the library and I'm having some issues during connection. The callback seems to be called twice with errors, when given this (invalid) url.

var amqp = require('amqplib/callback_api');

var amqpUrl = "amqp://username:[email protected]";

var counter = 0;

function output(err) {
    console.log('Error: ' + JSON.stringify(err));
    console.log(++counter);
}

amqp.connect(amqpUrl, {}, function(err, conn) {
    if (err) {
        return output(err);
    }
    console.log("No error");
});

I can confirm this -- the connect callback is called once with Error: Handshake terminated by server: 403 (ACCESS-REFUSED) with message "ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN., then a second time a couple seconds later with read ECONNRESET.

I confirm @SimonWoolf confirmation in 2017.

This is related to #266 - general connection error handling. We can read there - listen for 'error' on the connection object. But there is no connection object.
