[TIMOB-18333] iOS: Debugger creates unnecessary call-frames in debug view

Debugger creates unnecessary call-frames in 3.5.0. Two screenshots are attached to differentiate the behaviors in 3.5.0 and 3.4.1.

It's a regression since 3.4.1 works as expected

Steps To Reproduce

1. Create a classic App 2. Add following two JS files called app.js and import.js {panel:title=app.js}

Ti.include("import.js");

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

win.open(); 

{panel} {panel:title=import.js}

 
var x = 10;
Ti.API.info("x = "+x);

function imported(x) {
	var y = 'y';
	Ti.API.log("Imported function: x="+x+", y=",y);
}

{panel} 3. Place a breakpoint at line 2 of import.js file 4. Debug in iOS device. 5. Observe the call-frames in *Debug pane*

Actual Result

3 call-frames are observed and 2nd is unnecessary. See the screenshot *Screenshot_3.5.0.png*

Expected Result

2 call-frames observed. See the screenshot *Screenshot_3.4.1.png* *Note:* Variables in variable pane are grayed in 3.5.0 while 3.4.1 shows as green.
