Bug 22461: Fix LDAP user replication

Bug 22461: Fix LDAP user replication

From bug 20287:
-        $borrowernumber = C4::Members::AddMember(%borrower) or die "AddMember failed";
+        Koha::Patron->new( \%borrower )->store;
         C4::Members::Messaging::SetMessagingPreferencesFromDefaults( { borrowernumber => $borrowernumber, categorycode => $borrower{'categorycode'} } );

$borrowernumber is not updated with the value of the newly created patron

This patch restores the previous behavior (as well as the die)
