Upgrade Devise from 4.1.1 to 4.2.0.

This fixes an issue with Rails 5 and brings us up-to-date with the latest Devise release.

This also replaces the deprecated Devise::TestHelpers with Devise::Test::ControllerHelpers.

Changelog: https://github.com/plataformatec/devise/blob/v4.2.0/CHANGELOG.md#420---2016-07-01
