Bug 24324: Resolve error with delete_records_via_leader.pl

To test:

Have a record with the 000 position 5 set to "deleted" (record status)
Use koha-shell to run the job with the -i flag: perl misc/cronjobs/delete_records_via_leader.pl -c -i -v
* items and the record should be deleted
Mark another record with the 000 position 5 set to deleted (record status)
Use koha-shell to run the job without the -i flag: perl misc/cronjobs/delete_records_via_leader.pl -c -v
* if the record had items, it will not be deleted
* if the record did not have items, it will be deleted.
