Order of events being added to the adobeDataLayer array.

Is seems that the ACDL script is adding events to the `adobeDataLayer` array only after the callbacks of the events have completed. This leads to an odd ordering of the event entries in the `adobeDataLayer` array.

Consider the following script:
```html

window.adobeDataLayer = window.adobeDataLayer || [];

window.adobeDataLayer.push(function (dl) {
dl.addEventListener("one", function () {
logItemEvent("2: ", 0);
logItemEvent("2: ", 1);

dl.push({ event: "two" });

logItemEvent("3: ", 0);
logItemEvent("3: ", 1);
});

logItemEvent("1: ", 0);
logItemEvent("1: ", 1);

dl.push({ event: "one" });

logItemEvent("4: ", 0);
logItemEvent("4: ", 1);

function logItemEvent(prependText, item) {
if (dl[item] && dl[item].event) {
return console.log(prependText+"adobeDataLayer["+item+"].event = "+dl[item].event);
}
return console.log(prependText+"adobeDataLayer["+item+"] = "+dl[item]);
}
});

```

The resulting log output is:
```
1: adobeDataLayer[0] = undefined
1: adobeDataLayer[1] = undefined
2: adobeDataLayer[0] = undefined
2: adobeDataLayer[1] = undefined
3: adobeDataLayer[0].event = two
3: adobeDataLayer[1] = undefined
4: adobeDataLayer[0].event = two
4: adobeDataLayer[1].event = one
```

But the expected output would have been:
```
1: adobeDataLayer[0] = undefined
1: adobeDataLayer[1] = undefined
2: adobeDataLayer[0] = one
2: adobeDataLayer[1] = undefined
3: adobeDataLayer[0].event = one
3: adobeDataLayer[1] = two
3: adobeDataLayer[0].event = one
3: adobeDataLayer[1] = two
```

It would be expected that the ACDL appends the event object to the `adobeDataLayer` array prior to calling the callbacks that have been registered to that event, and not after. Because otherwise, notice how the events `one` and `two` end up in the reverse order.
