use following <script> and your page will be testable with protractor. this is simply confirm stable with no wait so you should wait for specific element to continue your test.

index.html

<script>
var Testability = (function () {
    function Testability() {}
    Testability.prototype.whenStable = function (callback) {
        callback();
    };
    return Testability;
}());
var testability = window._synctractor = window._synctractor || new Testability();
window.getAngularTestability = function (_element) { return testability; };
window.getAllAngularTestabilities = function () { return [testability]; };
</script>
