[TIMOB-4492] iOS:Internationalization of strings does not work on iphone if the project is built from xcode

This works fine when built and deployed from Ti Studio! Step1: Copy the below code to app.js Step2: Create a folder 'il8n/en' and 'il8n/es' in the root of the project. Step3: Copy the strings.xml files(attached) to both the folders. Step4: Run the application. You can a see a welcome message. Step5: Go to 'build/iphone' directory and open the project in x-code. Step6: Build and run the application from x-code. Step7: The strings.xml is missing in the project and internationalization does not work.

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

//
var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});


var label1 = Titanium.UI.createLabel({
	color:'#999',
	text:Ti.Locale.getString("welcome_message"),
	font:{fontSize:20,fontFamily:'Helvetica Neue'},
	textAlign:'center',
	width:'auto'
});

win1.add(label1);

win1.open();

The screenshot of the application is attached. Associated Helpdesk Ticket: http://appc.me/c/APP-762623
