Bug 19532: (QA follow-up) Fix fine calculation by inserting biblionumber

The fines cron job uses Getoverdues to pass issue info to CalcFine.
It took me a while to realize that the overdue hash does not contain
a biblionumber. When testing CalcFine, we pass an item hash that
does include one.

So what happened? $item->{biblionumber} is undefined when it comes from
Getoverdues and no recall overdue fine is calculated, only a regular one.

Simple fix (without any impact): Add a biblionumber to Getoverdues.

Tested with fines.pl: recall fine applied now.
Ran some Circulation and Overdues unit tests.
