To test:
1) Make sure syspref memberofinstitution is turned on
2) Add a new patron of organisation category (example: library)
3) Check that there is no field set 'organisation' showing up
4) Checkout books to any borrower
5) Renew books until no longer possible
6) Scan barcode from renewed book to force renewal
6) Check that the 'no more renewals' message has no empty pull below text message
