Fixed a bug when render <tr> attribute in IE browser

[dcais]

Tempo.exports.utils.getElement = function (template, html) {
    if (navigator.appVersion.indexOf("MSIE") > -1 && Tempo.exports.utils.equalsIgnoreCase(template.tagName, 'tr')) {
        // Wrapping to get around read-only innerHTML
        var el = window.document.createElement('div');
        el.innerHTML = '<table><tbody>' + html + '</tbody></table>';
        var depth = 3;
        while (depth--) {
            el = el.lastChild;
        }
        el.setAttribute('data-template', '');
        for (var a = 0; a < template.attributes.length; a++) {
            var attr = template.attributes[a];
            el.setAttribute(attr.name, attr.value);
        }

        return el;
    } else {
        //No need to wrap
        template.innerHTML = html;
        return template;
    }
};
