Bug 19750: Overdues without a fine rule add warnings to log

When running fines.pl, any overdue items that have no corresponding circulation rule will generate the following warning:

Use of uninitialized value $amount in numeric gt (>) at /usr/share/koha/bin/cronjobs/fines.pl line 133.

Test Plan:
1) Create a single circ rule
2) Backdate a checkout so it is overdue
3) Delete the circ rule
4) Run fines.pl, note the warning
5) Apply this patch
6) Run fines.pl, note the warning is gone
