iOS: Properties.setList - Ti.App.Properties.setList cannot save arrays that contain null, undefined, or empty values

Details: If you use Ti.App.Properties.setList() to save an array that contains null, undefined, or an empty value, then setList() will not save the array and return "Attempt to insert non-property value" message in xcode's console.

This is not a regression. Bug still occurs on 3.0.2.GA.

Also, Ti.App.Properties.setList() works as expected on Android; can save an array that contains null, undefined, or an empty value.

Steps to reproduce:
1. Install the following Titanium app to an iOS device:

var win = Ti.UI.createWindow({

	backgroundColor: 'white'

});

// same issue if there is null or undefined in the array

var vals = [,42];

Ti.App.Properties.setList('number', vals);

var label = Ti.UI.createLabel({

	text: (Ti.App.Properties.getList('number')[1] + ' monkies'),

	font: { fontSize:48 }

});

win.add(label);

win.open();

2. Launch app

Actual: iOS will not save vals array and return "Attempt to insert non-property value" message (see log.txt)

Expected: App should launch with "42 monkies" in the label like in Android (see android.png)

Note: This issue seems similar to TIMOB-11399
