    pathbar: Fix crash when right clicking
    
    button_data_free() was destroying the button_menu_popover because it
    was set as a child of the button previously.
    
    This means that the next time one right clicks a parent folder, we
    use a pointer to a destroyed object, crashing the application.
    
    Reparent to the pathbar before the button is destroyed.
