Bug 14015 - Checkout: Fix software error if barcode '0' is given

To reproduce the bug:
- Go to Home > Circulation > Checkouts > [a patron]
- Enter 0 (zero) in barcode field and hit Enter

Result:
Software error
  Can't use string ("1") as a HASH ref while "strict refs" in use
  at /usr/share/kohaclone/circ/circulation.pl line 473

To test:
- Apply patch
- Repeat steps above
- Verify that the sofware error is gone and that you get a
  message as with other invalid barcodes.
- Test with other values: '00', '000', existing barcode, barcode that does not
exist
- Test with empty barcode (for printing slip)
- Search for regressions

Note: I tried to create an item with barcode '0' to test that case as well, but
it was
      not possible. Giving the possibility to create an item with barcode '0'
is not in
      the scope of this bug.
