Bug 14122: Patron card: Software error when creating using borrower_number as parameter from URL

To test prepare an URL like the following:

...cgi-bin/koha/patroncards/create-pdf.pl?borrower_number=61&template_id=24&layout_id=21&start_card=1

Change the values for borrower_number, template_id and layout_id to something that exists in your system.

Without patch, the URL leads to a software error:
Can't use an undefined value as a HASH reference at /usr/share/kohaclone/patroncards/create-pdf.pl line 118.

With patch, a PDF with the patron card is created.

NOTE: This does NOT deal with the case where borrowernumber,
template_id, or layout_id are invalid. This only deals with
the case where they do exist.

Invalid borrowernumber still gives same error.
Invalid template_id or layout_id gives error on line 111.
Those are beyond the scope of this bug.
