LP#1780283 Checking One Bill Checks Them All

Under Patron->Bills->History if Bill # isn't visible for the Transactions
grid or Payment ID isn't visible for Payments grid, rows can't be selected
individually. This adds the required attribute to those field directives.

1. Under a patron account with multiple bills, go to Bills->History
2. Remove Bill # from the Transactions grid
3. Try to select an individual row (note all rows are selected)
4. Apply patch and repeat steps 1-3 (note rows are selected individually)
