Switch test to use a specific locale for which we have a message file (french). The default ResourceBundle behaviour is to attempt to load the platform locale if the specified one isn't found before using the default. We don't have a messages_en.properties file, hence trying to use "en" locale on a Chinese computer will result in Chinese messages being used (and test failing).
