$.fixture templated values not being included in callback data

[webbower]

If you set up a dynamic fixture with a templated URL, the originalOptions param of the callback will not be updated with the templated URL values if the data prop was not set in options of the AJAX call.

$.fixture('GET /todo/{id}', function(orig) {
    console.log(orig.data.id); // undefined
    console.log(orig.data); // undefined
});

$.ajax({
    url: '/todo/10',
    dataType: 'json',
});

I suspect the problem is that here https://github.com/jupiterjs/jquerymx/blob/master/dom/fixture/fixture.js#L62, if you try to merge an object into undefined with jQuery.extend, it fails. So if $.extend(originalOptions.data, data) equates to $.extend(undefined, { id: '10' }), then data isn't created.

The solution I devised involves checking to make sure the data property of originalOptions exists and if it doesn't, setting it to an empty object before calling jQuery.extend.
