Not fetching missing products

The plugin is not fetching all the products at first run. And later only fetches the products that haven been updated.

To fix this I changed auditRecords()

auditRecords: function() {
                    var local = this.pluck('id'),
                        self = this;

                    return this.getRemoteIds()
                        .then(function(remote) {
                            var add = _.chain(remote).difference(local).compact().value(),
                                remove = _.chain(local).difference(remote).compact().value();
                            self.enqueue(add);
                            self.dequeue(remove);
                            self.removeGarbage(remove);
                            return self.processQueue({
                                queue: add,
                                all: true
                            });
                        })
                        .done(function() { debug('audit complete'); })
                        .fail(function(err) { debug('audit failed', err); });

                },

Please confirm
