[TIMOB-7317] IOS: ImageView fires the load event with state 'url' instead of 'image'

   var win = Titanium.UI.createWindow({  
       backgroundColor:'#fff'
   });
    
   var imgView = Ti.UI.createImageView(
   {
       touchEnabled: false,    //if this is false: load event does not fire. If true it does!
       left:0,
       top:0,
       width: 100,
       height: 100
   });
    
   Ti.API.info("Adding load event listener");
    
   imgView.addEventListener('load', function(e){
       Ti.API.info("image loadded state is "+e.state);
   });
    
   imgView.image = 'http://docs.appcelerator.com/titanium/2.0/landing/appc_welcome.png';
    
   win.add(imgView);
   win.open();
