  Bug 19933: Remove patronflags - tricky ones

Test plan:
1 - Setup SIP in your testing environment
    https://wiki.koha-community.org/wiki/Koha_SIP2_server_setup
2 - Set a patron to have a restriction
3 - Send a patron status request or patron information command via
    the SIP cli emulator (see link above)
4 - Note the comment on the restriction is sent only once
