[Koha-patches] [PATCH] Prevent fines failure on NULL borrowernumber.

[Joe Atzberger]

The problem is that we do not ensure that the issues table has valid
borrowernumber in each line.  This is exacerbated by Getoverdues()
returning data sorted BY borrowernumber.  So one NULL borrowernumber
in issues prevented ALL fines from being assessed.  The actual error
from fines.pl cron log is:
  No branchcode argument to new.  Should be C4::Calendar->new(branchcode => $branchcode)
  at /home/user/kohaclone/misc/cronjobs/fines.pl line 98

This patch deals only with getting fines to avoid crashing.  It does
not fix the underlying data integrity problem.
