[TIMOB-2481] iOS: Push Notifications Bug

Hi,

I've tried the basic example below for push notifications, I get prompted to allow, then nothing happens, no error, no success, it fails silently. Unless I'm doing something wrong, the issue occurs on the latest 1.4 release as well as the latest 1.5 build.

Titanium.Network.registerForPushNotifications({
    types: [
        Titanium.Network.NOTIFICATION_TYPE_BADGE,
        Titanium.Network.NOTIFICATION_TYPE_ALERT,
        Titanium.Network.NOTIFICATION_TYPE_SOUND
    ],
    success:function(e)
    {
      alert(e.deviceToken);
    },
    error:function(e)
    {
        alert(e.error);
    },
    callback:function(e)
    {
        alert("Received a push notification\n\nPayload:\n\n"+JSON.stringify(e.data));
    }
});
