[TIMOB-6368] iOS: Setting headers outside of table view row creation crashes the app

// 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 win = Titanium.UI.createWindow({  
    backgroundColor:'#fff'
});

var table = Titanium.UI.createTableView({});
win.add(table);
win.open();

var addrow = function(){
	
		var row = Ti.UI.createTableViewRow({
			height:65
		});
		
		var photo = Ti.UI.createImageView({
	        // image: ,
	        top: 12,
