Bug 34258: pass an unblessed hash to AddIssue()

Bug 34258: pass an unblessed hash to AddIssue()

In Koha 23.05, we lost the ability to renew an item via SIP2.

The relevant commit is ddc2906b77 from Bug 31735, where the
file C4/SIP/ILS/Transaction/Renew.pm was modified to no longer
pass an unblessed $patron hash to C4::Circulation::AddIssue()

This patch fixes that.

Test plan:

1) Using the SIP emulator, check out an item to a patron, then
   try to renew it. Example commands for a KTD instance:

   $ misc/sip_cli_emulator.pl -a localhost -p 6001 -l CPL -su term1 -sp term1 -m checkout --patron koha --item 3999900000001
   $ misc/sip_cli_emulator.pl -a localhost -p 6001 -l CPL -su term1 -sp term1 -m renew --patron koha --item 3999900000001

   Notice that the second command will fail!

2) Apply this patch.

3) Repeat the 2nd command -- this time the renewal should work.

4) Run the SIP-related unit tests, they should all pass:

   $ prove t/db_dependent/SIP/
   t/db_dependent/SIP/ILS.t .......... ok
   t/db_dependent/SIP/Message.t ...... ok
   t/db_dependent/SIP/Patron.t ....... ok
   t/db_dependent/SIP/SIPServer.t .... ok
   t/db_dependent/SIP/Transaction.t .. ok
