Return $promise in route resolve

[lithammer]

Imagine the following code snippet:

function('NotesCtrl', function(notesList) {
    console.log(notesList);
}

Without returning $promise, this will always print []. However with $promise it will print the actual list of items returned from the server.

Shouldn't controller be instantiated only when NotesService.Query() gets data? I'm not sure about that, this evening I'll investigate and merge your PR, thanks for that

Here's what little documentation I could find about it:

$promise: the promise of the original server interaction that created this instance or collection.

On success, the promise is resolved with the same resource instance or collection object, updated with data from server. This makes it easy to use in resolve section of $routeProvider.when() to defer view rendering until the resource(s) are loaded.
