Sometimes Zeitwerk messes up on CI action

[pedantic-git]

Sometimes when running the tests on the new GH Actions, we get an error like:

/home/runner/work/name.pn/name.pn/vendor/bundle/ruby/3.1.0/gems/devise-4.8.1/lib/devise/mailers/helpers.rb:5:in `<module:Mailers>': uninitialized constant Devise::Mailers::Helpers (NameError)

This suggests to me a Zeitwerk issue with files loading in the wrong order.

It's not a huge deal because rerunning the tests works, but it would be good to get to the bottom of it.
