This PR fixes I18n.locale for rake middlewares. Mastodon uses Devise that depends on Warden.
Warden::Manager can be found in rake middleware. It is outside of the controller.

In the case of authentication failed, warden calls throw(:warden). At the time Warden::Manager
delegates request to failure_app to generate response and flash[:alert] after catching it.
Unfortunately, I18n.locale is already reset then because I18n.with_locale is enabled only
inside the controller. If we used I18n.locale=, Devise::FailureApp could get the current locale.

* Use explicit reference to flashes partial from admin layout

Because some of the controllers which use the admin layout do not inherit from
application controller, this partial is not in their view path.

Hide some components rather than unmounting them to allow to show again
quickly and keep the view state such as the scrolled offset.
