[TIMOB-18309] iOS: Debug - Variable changed to another object variable doesn't show its properties in variables view

When variable is changed to another object variable, It doesn't show its properties in debug variable view. Please see the attachment to see the variables view in Studio.

It's a regression since it works in 3.4.1 GA

Steps to reproduce

1. Create a classic project 2. Copy following code in app.js file

var y = {foo:'bar'};

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

var b = Ti.UI.createButton({
	title:"Shadowing",
	width:140,
	height:40,
	top:260
});
b.addEventListener('click',function() {
	var x = "foo";
	Ti.API.info("Shadow x: "+x);
});
win.add(b);
win.open();

3. Place a breakpoint in line 15 ( @ var x = "foo"; statement) 4. Debug in iOS device 5. Press the "Shadowing" button to trigger the breakpoint 6. In the Variables pane, change value of x to y (not string; variable) by double-clicking in the Value column {noformat} x should display [object Object]. It works! {noformat} 7. Expand the x

Actual Result.

{noformat} x doesn't have property foo inside it. Please see the screenshot for more info. {noformat}

Expected Result

{noformat} x should have [object Object] with foo == bar {noformat}
