[CURA-11102] qml warnings

[wawanbreton]

• The first mentioned QML warning has been fixed already with commit 1f67452
• Fixed two other QML binding loop warnings.
  • The one in Menu.qml implies that the width of the menu will not automatically change if any of the menu item changes. It will be updated only when the menu is opened again. In practice, this does not happen because it would be very user-unfriendly to have a menu that changes its width while the mouse cursor is over it.
