Function clearPersistedLocalePreference

Clear the locale preference previously presisted to localStorage

If you are doing this, you should probably call setLocale or i18next.changeLanguage (depending on your setup) immediately before this with convertToSupportedLocaleOrDefault(getPreferredLocale()) so the current locale is set to user's preferred locale.

Note if persist is true when initializing, subsequence setLocale calls will still persist the value.
