[nautilus-actions] Duplicate the candidate profile, setting its parent to Null

[Pierre Wieser <pwieser src gnome org>]

commit e8d84dde3c25e9921a945244930c79fba992e172

    Duplicate the candidate profile, setting its parent to Null
    
    This prevents Nautilus to crash when trying to unref the previous profile, thus trying to unref
    a no-more existing parent.
