Bugfix: only reset menu if a new sub menu is created: In the previous version a short black screen (blink) happend while changing parameters. Root cause was that the menu structure was reset while no submenu was created because the value update happend at the actual menu. This has been fixed by only resetting the menu if it is really needed
