    properties-window: Don't change permissions in Trash
    
    Currently there is a menu which allows changing the permissions
    for trashed files.
    
    This is unintended behaviour since changing the permissions for
    trashed files is not supported anyway, resulting in an error
    message or even Segmentation Fault.
    
    This patch solves this issue by removing the permission access
    menu for trashed files.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/issues/432
