Bug 35278: Fix warn from column_settings.pl

We need to add scalar to the calls. These parameters are not meant
to be used as multi_param.

Test plan:
Try With and without this patch on staff:

Try: /cgi-bin/koha/admin/columns_settings.pl
=> WITHOUT: No warnings
=> WITH: Same. No change.
Try: /cgi-bin/koha/admin/columns_settings.pl?module=acqui&page=basket
=> WITHOUT: Opens module, scrolls down. CGI::param called in list context in logfile
=> WITH: Opens module, scrolls down.
Try: /cgi-bin/koha/admin/columns_settings.pl?module=acqui&page=basket&table=orders
=> WITHOUT: Opens module, scrolls down. CGI::param called in list context in logfile
=> WITH: Opens module, scrolls down.

Try: /cgi-bin/koha/admin/columns_settings.pl?module=acqui&module=admin
* Hash like: panel => acqui, admin => page, undef  => table, undef => modules, $modules (SHIFTED)
=> WITHOUT: Acqui expanded showing: There is no page using the table configuration in this module.
=> CGI::param warning in log.
=> And: Problem = a value of table has been passed to param without key
=> And: Problem = a value of modules has been passed to param without key
=> WITH: Only the first module (Acqui) should be expanded.

Try: /cgi-bin/koha/admin/columns_settings.pl?module=acqui&module=admin&page=basket&table=orders
* Hash like: panel => acqui, admin => page, basket => table, orders => modules, $modules hash (SHIFTED)
=> WITHOUT: Acqui expanded showing: There is no page using the table configuration in this module.
=> And: CGI param log warning.
=> WITH:: Opens Acqui. Second module ignored. Scrolling.

Try: /cgi-bin/koha/admin/columns_settings.pl?module=admin&module=acqui&page=basket&table=orders
* Hash like: panel => admin, acqui=> page, basket => table, orders => modules, $modules hash (SHIFTED)
