Unsaved children are not able to be saved when updating parent object

[TylerBrock]

Adding to our list of items in #73.

In the below code we make two classes Brand and Item. Let's say that Brands can have many Items and that this relationship is modeled by an array of Item pointers set on the "items" field for Brand.

We then create a new Item and Brand, setting the item as an array of pointer on brand.

It saves just fine. Parse realized that item is unsaved and persists it before saving brand. It follows up by saving brand and resolving the promise.

However, if we then try to add unsaved objects to the already persisted brand it becomes unable to save the unsaved objects giving the error:

"Cannot create a pointer to an unsaved ParseObject"

Setup

'use strict';

var Parse = require('parse/node');

class Brand extends Parse.Object {
  constructor(attributes, options) {
    super('Brand', attributes, options);
  }
}
Parse.Object.registerSubclass('Brand', Brand);

class Item extends Parse.Object {
  constructor(attributes, options) {
    super('Item', attributes, options);
  }
}
Parse.Object.registerSubclass('Item', Item);

Test

var item = new Item();
var brand = new Brand({items: [item]});
brand.save().then(function(savedBrand) {
  console.log('works fine');

  var item2 = new Item();
  var brandItems = brand.get('items');
  brandItems.push(item2);
  brand.set("items", brandItems);

  // parse should save unsaved items successfully here
  return brand.save().then(function(updatedBrand) {
    console.log('cool');
  });
});

This seems like a bug. It works just fine in the 1.5 SDK. Please let me know what you think. Also I'd love to help fix it if you point me in the right direction. Anything I can do to help, let me know.
