Checks if an incoming change to settings.language is a change to the existing settings
Currently the assumption is that if a settings.locale_variant slug exists, then that is the current language

@param  {String}  languageSettingValue the newly-set language slug string.
@param  {Object}  settings user settings object.
@return {Boolean} if the language setting has been changed.
