    app: fix error reporting in gimp_tool_preset_deserialize_property()
    
    when setting a custom parse error with g_scanner_error() we *must*
    return G_TOKEN_NONE as expected token, or general GimpConfig error
    handling will try to overwrite our error with its generic "unexpected
    token" message, which triggers a warning.
