[TIMOB-6460] iOS: App always launches to non-retina iOS Simulator

Problem

App always launches to non-retina iOS Simulator. It doesn't matter whether you build the app, then select retina, then build the app again. It will launch the non-retina screen.

REGRESSION - that used to work with the old version of CI build 1.8.0.1v20111118152656

Reproducible Steps

1. Build the sample code 2. When the simulator appears switch to Retina screen 3. Build the app again

Sample Code

// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000');

//
// create base UI tab and root window
//
var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});

win1.open();
