Bug 17783: Prevent crash when providing an undefined value

When calling the proposed version of get_effective_issuing_rule with undefined
parameter values, a following crash occurs:

SQL::Abstract::puke(): [SQL::Abstract::__ANON__] Fatal: SQL::Abstract before v1.75
used to generate incorrect SQL when the -IN operator was given an undef-containing
list: !!!AUDIT YOUR CODE AND DATA!!! (the upcoming Data::Query-based version of
SQL::Abstract will emit the logically correct SQL instead of raising this
exception) at /home/ubuntu/kohaclone/Koha/Objects.pm line 182

This patch adds a test to cover this problem and fixes the issue.

To test:
1. Run t/db_dependent/Koha/IsssuingRules.t
