Order totals and payment status are not recalculated after splitting shipment

[vzqzac]

Steps to reproduce

1. Place an order with (at least) 2 line items in the cart
2. Go to the admin panel and select the placed order
   (Optional) Capture the pending payment
3. Split the created shipment into 2 separated shipment with the usual flow
4. Verify how order totals (total, ship total, tax)
   If you captured the payment, check how payment status didn't change from paid to balance due

Expected behavior

Ship total should change (double)
Tax total should change (double, based on the shipping method's tax rate)
Order total should reflect the increase of ship total and tax total
Order's payment status should change from paid to balance due if the payment was captured

Actual behavior

New shipment is created properly but order is not updated, totals nor payment status
