TIMOB-25192

Evaluating .NET null value in async crashes app.

var win = Ti.UI.createWindow({ backgroundColor: 'green' });
var PopupMenu = require('Windows.UI.Popups.PopupMenu');
var UICommand = require('Windows.UI.Popups.UICommand');
var Point = require('Windows.Foundation.Point');

var menu = new PopupMenu();
var alertHiCommand = new UICommand("Hi!");
var alertByeCommend = new UICommand("Bye!");

var commands = menu.Commands;
commands.Add(alertHiCommand);
commands.Add(alertByeCommend);

function popupMenu(e) {
    var p = new Point(e.y, e.x);
    menu.ShowAsync(p).then(function (selectedCommand) {
        if (selectedCommand == null) {
            alert('nothing selected');
        } else {
            alert(selectedCommand.Label);
        }
    }, function (err) { alert(err) });
}

win.addEventListener('click', function (e) {
    popupMenu(e);
});

win.open();

Expected: No crash when you click app window (popup appears) and then you should be able to click elsewhere to cancel popup.
