[TIMOB-18545] iOS: ImageView load event is not triggered in 64 bits build

Problem Description

The load event in an ImageView is not being triggered in 64 bits build, only happens with the 64 bit build (i.e. , this doesn't happen in the app in 32 bits build, like when you compile with 3.4.1).

Steps to reproduce

1. Create a new Mobile Project (Classic Titanium) 2. Replace app.js with this:

var win = Ti.UI.createWindow({
	backgroundColor:'white',
});
setTimeout(function() { 
var image  = Ti.UI.createImageView({
    image:'KS_nav_views.png',
    touchEnabled:false,
});

image.addEventListener('load',function(){
	Ti.API.info('loaded');
});
win.add(image);
},1000);

win.open();

3. Run it in device or simulator

Actual Results

The load even is never triggered (i.e., no 'loaded' message in the console).

Expected Results

The load event to be triggered (and the 'loaded' message appearing in the console).

Extra info

This won't happen when compiling with 3.4.1, even in the same device. Only happens with 64 bits build.
