Bug 25262: [19.05.x] Do not truncate MANUAL_INV in dropdown

There is an issue in that historic values will still be truncated, but recent values are not.
I feel the cash register report should reflect recent transactions over historic, and the historic are a data cleanup issue

To test:
1 - Add a MANUAL_INV value with more than 5 characters 'INCREDIBLE_HULK'
2 - Add a manual invoice to a patron's acccount using this value
3 - Note the full code displays in patrons account
4 - Browse to Reports->Cash register
5 - Search for today's date, the value you createed, and all libraries
6 - No results returned
7 - Apply patch
8 - Repeat 5
9 - The transaction shows
