* Eager autoload mail gem when eager load is true We had a production issue where our Sidekiq worker threads all became deadlocked while autoloading a file within the mail gem, required via ActionMailer, despite setting our Rails applicaiton to eager load. `Mail.eager_autoload!` exists and works great, ActionMailer just doesn't call it during eager loading. Adding it to the ActionMailer Railtie's eager_load_namespaces takes care of calling `Mail.eager_autoload!` during the `eager_load!` initializer. * 'Mail' isn't defined yet, use before_eager_load instead * Make sure mail is loaded * Move eager load of Mail into ActionMailer.eager_load!
