Reassigning an order from the order entity page redirects to orders view

When you click the "Reassign order" button on an order entity screen (/admin/commerce/orders/#) you are dumped onto the orders view instead of the order you just reassigned.

Now if further edits need to be made to the order the administrator needs to search for that order and open it again. Redirecting to the orders view only makes sense if you reassign from the orders view.

The reassign order form needs to take into account the page the user was on before reassigning the order.
