issue #2852

added a missing argument

Fixes #802: Added support for retrieving sub-array element or child object property through `ArrayHelper::getValue()`

Test code
```php
$orders = $this->getSort()->getOrders();
ArrayHelper::multisort($data, array_keys($orders), array_values($orders));
```

Appended newlines to every PHP document that did not have a newline as the last character in the file.
