Bug 28271: Add the ability to set a new lost status when a claim is resolved

When a claim is resolved the librarian should be able to edit the lost
status of the item.

It is also letting a way out when BlockReturnOfLostItems is set (the
lost status is stuck on ClaimReturnedLostValue as we remove the
option to edit itemlost on the item edit form).
