What is this pull request for?
If an app that uses Alchemy has it's
::I18n.available_locales
array restricted to only a few locales, but the user's browser or a stale:alchemy_locale
session value request one that is not listed as available, set the session to the default locale.In cases where the app has
enforce_available_locale
set to `true, the previous behaviour would raise an error - which would make Alchemy unusable because of an unavailable locale.
