Bug 23403: Remove cardnumber from SIP

Bug 23403: Remove cardnumber from SIP

== Test plan ==
1 - Have two patrons with userids and no cardnumber
2 - Note which of these has the higher borrower number
3 - Use the SIP cli emulator to connect and checkout a book to the patron with higher borrowernumber
      See example after
4 - Note the book may checkout to the wrong patron!
5 - Apply patch
6 - Checkout to both patrons via sip
7 - The patrons get the correct checkouts

=== SIP CLI emulator ===
./misc/sip_cli_emulator.pl -a 127.0.0.1 -p 6001 -su term1 -sp term1 \
-l CPL --patron 23529001000463 -m checkout --item 39999000001259

translation: via the koha user term1, checkout item 39999000001259 to
patron 23529001000463
