            Fix error trying to save CSD settings.

            Because of the ordering of assignments in ChannelSettingsDialog's ctor,
            we weren't assigning the global config before passing it in to the
            list modes pane. This caused NPEs if toggling the 'show extended info'
            option and saving.
