Bug 17775 - Add new user with LDAP not works under Plack

This patch fixes internal server error:

Undefined subroutine &C4::Auth_with_ldap::AddMember called at /srv/koha_ffzg/C4/Auth_with_ldap.pm line 213.

It occurs only under plack, and it's strange since C4::Members
does EXPORT AddMember and we are importing it into Auth_with_ldap.pm
(and it does work under CGI).

I did not test but trust author and signoffer. The change cannot hurt.
