Bug 37016: Invalid due date in SIP renew response

Test plan using koha-testing-docker:

1) Make sure SIP is running.  You may need to edit
   /etc/koha/sites/SIPconfig.xml and remove the 8023 connector and
   restart the SIP-server (koha-sip --restart kohadev)
2) Find a patron, say 23529000197047
3) Set a password by selecting "change password", set it to
   "Password1234"
4) Find a book, say 39999000000856
5) Issue book to patron with sip-client:
   sudo koha-shell -c "/usr/share/koha/bin/sip_cli_emulator.pl \
                      --address localhost --port 6001 -t cr \
                      --su term1 --sp term1 --message checkout \
                      --location CPL --item 39999000000856 \
                      --patron 23529000197047 --password Password1234"\
                      kohadev
6) Note the AH-header in the response which for example:
   'AH20240619    235900'
7) Make a renewal with:
   sudo koha-shell -c "/usr/share/koha/bin/sip_cli_emulator.pl \
                      --address localhost --port 6001 -t cr \
                      --su term1 --sp term1 --message renew \
                      --location CPL --item 39999000000856 \
                      --patron 23529000197047 --password Password1234"\
                      kohadev
8) Make sure the AH-header in the response is different from the
   response to the checkout, for example: 'AH20240624 235900'
