SSR component render() toString method returns undefined

[dschulten]

When using ${app.render()} in a template literal, I get undefined. That seems to be caused by a bug in toString():

var result = { head: '', addComponent: addComponent };
...
var html = AddToCart._render(result, state, options);
return {
    html: html,
    head: result.head,
    css: { code: cssCode, map: null },
    toString: function toString() {
        return result.html;                <-- probably should return html
    }
};

Workaround: use ${app.render().html} in template literals.
