Text to go in the release notes:
This fixes the cause of unnecessary "use of uninitialized value" warnings in the log files generated by Circulation > Renew (/cgi-bin/koha/circ/renew.pl). This was caused by not taking into account that the "barcode" parameter for this form is initially empty.

Bug 27549: "use of uninitialized value" warning on renew.pl

On the beginning we have empty "barcode" parameter for this form, but that not taken into account in regular expression  warning emitted: "Use of uninitialized value $barcode in substitution (s///) at /usr/share/koha/intranet/cgi-bin/circ/renew.pl line 47." in renew.pl
Fixed by making $barcode to become an empty string by default.

To reproduce:
    1) Head over to the "Circulation -> Renew" page.
    2) Check intranet-error.log there will be a warning "Use of uninitialized value $barcode in substitution (s///) at /usr/share/koha/intranet/cgi-bin/circ/renew.pl line 47".
    3) Apply the patch, refresh the "Renew" page.
    4) Ensure that the new "use of uninitialized value" warnings didn't appear in the console.

- When using koha-testing-docker the warnings are logged to /var/log/koha/kohadev/plack-intranet-error.log
