-    $data{'userid'} = Generate_Userid($data{'borrowernumber'},
$data{'firstname'}, $data{'surname'}) if $data{'userid'} eq '';
+    $data{'userid'} = Generate_Userid( $data{'borrowernumber'},
$data{'firstname'}, $data{'surname'} )
+      if ( $data{'userid'} eq '' || Check_Userid( $data{'userid'} ) );

Check_Userid returns 1 if it is unique.  So this means unique userids
will always be discarded and new ones created.

This is why all the tests depending on a userid are now failing

To test

1/ run perl t/db_dependent/Serials_2.t
2/ Notice lots of tests fail
3/ OR Add a borrower with a userid set, notice the userid is ignored
and one is generated instead
4/ Apply patch
5/ Add a new borrower, notice the userid sticks (if it is unique)
6/ Run perl t/db_dependent/Serials_2.t notice tests pass
7/ Run perl t/db_dependent/Members.t notice tests still pass
