Bug 26083: Item editor defaults to lost

When editing an item via additem.pl, koha defaults to the first
available lost status, rather than defaulting to not-lost.

Test Plan:
1) Ensure you do not have a value ClaimReturnedLostValue
2) Edit an existing item that is not lost
3) Note the lost value is set even though it is not lost
4) Apply this patch
5) Edit a different item that is not lost
6) Note the lost value is not set!
