When running these tests, under certain conditions, we get a warning
followed by an error:
```
activesupport-6.1.7.7/lib/active_support/dependencies.rb:502:
warning: already initialized constant ActiveStorage::Representations
activesupport-6.1.7.7/lib/active_support/dependencies.rb:502:
warning: previous definition of Representations was here
Failure/Error: raise LoadError, "Unable to autoload constant
'#{qualified_name}', expected #{file_path} to define it"
LoadError: Unable to autoload constant
ActiveStorage::Representations::RedirectController, expected
activestorage-6.1.7.7/app/controllers/active_storage/representations/redirect_controller.rb
to define it
```
The error seems to take place when we request a page in a test that
loads two (or more) ActiveStorage images if ActiveStorage hasn't loaded
yet, although it's a flaky error and so the test doesn't always behave
like this.
We've tested that switching to zeitwerk solves the issue but, since we
aren't switching to zeitwerk in version 2.1.1 and we'd like this version
to run all tests correctly, for now we're changing the tests so they
don't load two records with images.
On of these tests ("Polls Index Polls can be listed") fails on my
machine when run individually. I haven't been able to consistently
reproduce the other ones.
