To test:
1. Go to any record
2. Hit the edit button on an item in the holdings table
3. Modify the URL so that the query param for the itemnumber is either
    3.1 empty: /cgi-bin/koha/cataloguing/additem.pl?op=edititem&biblionumber=384&itemnumber=
    3.2 an itemnumber that doesn't exist:
      /cgi-bin/koha/cataloguing/additem.pl?op=edititem&biblionumber=384&itemnumber=9999999999
    3.3 whatever else you come up with..
