[TIMOB-5387] Tabgroups don't work with fastdev

// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000')
 
var tabGroup = Titanium.UI.createTabGroup();
  
var win = Titanium.UI.createWindow({
    title:'win_test'
});
  
var webView = Titanium.UI.createWebView({
    html: '<select name="selectBox"><option value="val1">Value 1</option><option value="val2">Value 2</option><option value="val3">Value 3</option></select>'
});
win.add(webView);
  
  
var tab = Titanium.UI.createTab({
    icon:'',
    title:'Test',
    window:win       
});
  
tabGroup.addTab(tab);
tabGroup.open();
