recalculate prices does not work if package price changes

[PiQuer]

To reproduce, create an order, then change the agegroup so that the prices changes, try to recalculate the package price in the Admin panel.

Fatal error: Call to a member function getValue() on null in /var/www/ers/module/Admin/src/Admin/Controller/PackageController.php on line 361

As a workaround for my particular case where I needed to recalculate the price, I commented out these lines, because I know that the order is not paid.

#if($newItem->getStatus()->getValue() == 'paid') {
#     $newItem->setStatus($statusOrdered);
#}

I think I fixed this bug in the new master branch. Can you please have a look if the code of the master branch works for you?
