'Lost and paid' aged to lost items that are returned must have lost item fees refunded as is done with declared lost items

Product Owner thought that all 'Lost and paid' items would be refunded when a lost item was returned (can't renew a 'Lost and paid' item). She learned while testing CIRC-845 that this is not true. Only items formerly 'Declared lost' are refunded even after their status changes to 'Lost and paid'. We need the same behavior for items formerly 'Aged to lost' after their status changes to 'Lost and paid'. As always, the Lost Item Fee Policy settings must be followed to determine if a fee is refundable (for example, "If lost item returned, remove lost item processing fee" and "No fees/fines shall be refunded if a lost item is returned more than X <intervals> late").
