[TIMOB-26859] Android: Something broken with tabsBackgroundColor &tabsBackgroundSelectedColor on TabGroup refactoring -regression

// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000');
 
// create tab group
var tabGroup = Titanium.UI.createTabGroup({
//Test tabsBackgroundColor and tabsBackgroundSelectedColor here.
 tabsBackgroundSelectedColor:'red',
 tabsBackgroundColor:'blue'
 
});
 
var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});
var tab1 = Titanium.UI.createTab({  
    backgroundColor: 'yellow',
    backgroundSelectedColor: 'red',
    icon:'KS_nav_views.png',
    title:'Tab 1',
    window:win1
});
 
var label1 = Titanium.UI.createLabel({
    color:'#999',
    text:'I am Window 1',
    font:{fontSize:20,fontFamily:'Helvetica Neue'},
    textAlign:'center',
    width:'auto'
});
 
win1.add(label1);
 
//
// create controls tab and root window
//
var win2 = Titanium.UI.createWindow({  
    title:'Tab 2',
        backgroundColor:'#fff',
