commit 58e932c607db27bea2872625661991fb16c79d13

    [Task Manager] Parent QAction to "parent" instead of this
    
    This ensures the QAction is disposed of once the menu gets destroyed rather than
    accumulating forever - the methods already took a "parent" argument,
    which is passed the menu from QML side, for exactly that purpose.
