Bug 22927: Do not check an already lost item when marked as withdrawn or damaged

Due to how moredetail.pl was written it was hard to know which action
was triggered.

Test plan:
- Set MarkLostItemsAsReturned to "from the items tab of the catalog
module."
- Check an item out to a patron
- Use additem.pl to set that item to a lost status without returning it
- go to moredetail.pl for that item
- mark item as either damaged or withdrawn without interacting with the
lost dropdown
- note that item has not been returned

Note for QA: Maybe we could have just tested if exists $item_changes->{'itemlost'}
to call LostItem
