$ undefined in vows callback about tobi

[psd]

This is issue with vows not passing more than one parameter. Vows assumes callbacks(err, res, ..) so if err is set, the remaining parameters are undefined.

A work-round is to not use the vows callback directly, but insert a null err value, e.g.::

    browser.get('/register', function (res, $) {
        this.callback(err, res, $);
    });

This helped me get around the null problems, however the tobi objects now have no statusCode attribute.
