[Order States] Resumed orders (after cancelling) not displayed in the customer account -> mismatch on customer balances

[filipefurtad0]

Description

After cancelling and resuming an order (order state = resumed) the customer balance on /customers and the bulk coop (payments) report correctly reflects customer balance.

However, these orders cannot be found on the customers account account#/orders, both from the tabs "Orders" and "Transactions". This can leads to mismatches between the balance seen by the customer vs. the admin.

Expected Behavior

Resumed orders appear under the customers account account#/orders, on the tabs "Orders" and "Transactions" (=> correct customer balance)

Actual Behaviour

Resumed orders are missing from the customers account account#/orders, on the tabs "Orders" and "Transactions". (=> incorrect customer balance)

Steps to Reproduce

As admin:

1. Cancel an order.
2. Resume the order.
3. Log in as customer.
4. Look for that order under account#/orders
5. See it's missing both from Orders and Transactions.

If/when we fix this we then might need to consider re-opening #5505.
