Before this fix, I don't know if those emails would work having newlines in them.
`:mailer` is needed to pick it easily, while `type: :mailer` is needed for picking it automatically for tests located in spec/mailers/*_spec.rb It's a bit complicated in spec/services/notification_service_spec.rb but we'll leave it alone for now.
- Ignore JS fixtures - Ignore qa directory - Rewrite concern specs to put concern name first
