[TIMOB-1342] Custom Labels for contact phone numbers cause a crash

A customer reported that when they access a custom label in the contacts this causes the app to crash. I have been able to reproduce this on OS 4 and our latest from HEAD.

Code:
var contacts = [];
contacts = Titanium.Contacts.getAllPeople();

for (var i = 0; i < contacts.length; i++) {

var c = contacts[i];

//var fName = c.fullName.replace(/[^a-zA-z0-9 ]/g, '');

   try {
    Ti.API.log(c.phone);
   }
   catch(err)
   {
    Ti.API.log('ERROR: '+err);
   }

};
