Subject: Do not delete sub menus of the control menu explicitly

Do not delete sub menus of the control menu explicitly

This is not necessary because the sub menus are children of the main
menu, such that they are deleted together with the other actions by
QMenu::clear().

This prevents a crash that can happen if a sub menu is open while
another menu action is clicked.

Thanks to Fabian Vogt and Wolfgang Bauer for investigating this issue!
