[TIMOB-2344] Android: Crash when hiding Switch

var win = Ti.UI.createWindow({
    top: 0, left: 0, right: 0, bottom: 0,
    backgroundColor: 'black'
});

var data = [];
var row = Ti.UI.createTableViewRow({title: "Test Row", hasChild: true});
data.push(row);

var tbl = Ti.UI.createTableView({
    data: data,
    top: 100, left: 0
});
win.add(tbl);

var menu = Ti.UI.Android.OptionMenu.createMenu();
var editBtn = Ti.UI.createButton({
    title: 'Edit',
    top: 0, left: 0
});

editBtn.addEventListener('click', function() {      
    for (var i in tbl.data) {
        for (var j=0 ; j < tbl.data[i].rowCount ; j++) {
            var row = tbl.data[i].rowAtIndex(j);
            if (!row.cb) {
                row.cb = Ti.UI.createSwitch({
                    visible: !row.hasChild,
                    style: Ti.UI.Android.SWITCH_STYLE_CHECKBOX,
                    right: -5, // Negate the built-in pad
                });
                row.add(row.cb);
            }
            
            row.hasChild   = !row.hasChild;
            row.cb.visible = !row.cb.visible;
        }
    }
    tbl.data = tbl.data;
});
win.add(editBtn);
win.open();

Click the menu button once, everything toggles as expected. Click it a second time, crash.
