Bug 27180: Update fines on holidays

This patch removes code that prevents fines from being update on holidays.
The fines are already being calculated, and that takes the calendar into account if
needed, so fines won't be assessed on holidays if they shouldn't.

To test:
 1 - set finesCalendar to 'ignore'
 2 - Checkout an item due yesterday
 3 - Ensure circ rules have a fine amount set
 4 - Make today a holiday
 5 - run fines.pl
 6 - No fine assessed
 7 - Apply patch
 8 - run fines.pl
 9 - Fine assessed!
10 - set finesCalendar to 'use'
11 - checkout an item, due yesterday
12 - run fines.pl
13 - no fine assessed
