Bug 35983: Remove extra selected=selected from dropdown menu

To test:
1. Admin > Circ & fine rules
2. Select a library at the top of the forms ( #selectlibrary )
3. Try to change the 'Refund lost item replacement fee' to "Refund lost item charge (only if unpaid)".
4. Press save and let the page reload.
5. Look at the dropdown again, the value is now set to "Refund lost item charge and restore overdue fine".
6. APPLY PATCH
7. Try steps 2 - 5 again but this time the value in the dropdown should not change.
