[TIMOB-15772] Map Annotation w/ Custom Image not Draggable

Problem Description

If you have a Map View and add an annotation that has the "image" variable set with a custom image icon instead of a built in pin and you also have "draggable" set to true, you can not drag the pin around. If you drag the pin around on the map it will pick it up and let you drag it to a new location. However, if you then drag the map around (not the pin) the annotation is locked into a pixel location on your screen and doesn't move with the map. It is not locked into a GPS location on the Map View.

Steps to reproduce

1. Create a new project 2. Paste test code in app.js

var win = Ti.UI.createWindow();
 
var mountainView = Titanium.Map.createAnnotation({
    latitude : 37.390749,
    longitude : -122.081651,
    title : "Appcelerator Headquarters",
    subtitle : 'Mountain View, CA', 
    draggable  : true, 
    image  : '/images/pin.png',
});
 
var mapview = Titanium.Map.createView({
    mapType : Titanium.Map.STANDARD_TYPE,
    region : {
        latitude : 37.390749,
        longitude : -122.081651,
        latitudeDelta : 0.04,
        longitudeDelta : 0.04
    },
    animate : true,
    regionFit : true,
    userLocation : true,
    annotations : [mountainView]
});
 
win.add(mapview);
  
win.open();

3. Now run on iOS 7 with simulator 7.0 4. Randomly Click on map and annotation 5. Now, drag the pin around the map. Next, drag the map view around
