Paul Davis 03db585f24 do not delete display (context) menu when adding a new automation child lane
The manu is rebuilt every time it is required, no need to delete it. In addition, deleting it
in the middle of an event handler causes memory corruption because the entire menu (with all
items and submenus) is deleted before event handling for the menu is completed
