    properties: Don't attempt to setup_star if parent_location == NULL
    
    When you open a properties window on the root file system,
    you'll get
    g_file_has_prefix: assertion 'G_IS_FILE (file)' failed
    because setup_star is checking if the parent location can be starred.
    We only allow starring files in the home directory anyways, so just
    return early
