Pass locale with activatable / timeoutable hooks (#5815)

We need to explicitly pass the `locale` around from the options (passed
to `warden.authenticate!` for instance) or the `I18n.locale` when
logging out and redirecting the user via `throw :warden`, otherwise in a
multi-locale app we'd lose the locale previously set / passed around and
fallback to the default for that flash message.

This is a follow-up of the fixes in #5567 where we implemented the
locale passing logic down to the failure app, but it missed these places
where we were using `throw :warden`.

Closes #5812
