Minitest 5.25.2 introduces NameError: wrong constant name

[stathis-alexander]

When running tests with minitest 5.25.1, we see no errors. After bumping minitest to 5.25.2, all tests using shoulda-context fail with a similar message:

Error:
[TestDescription] :
NameError: wrong constant name

bin/rails test /usr/local/bundle/gems/shoulda-context-2.0.0/lib/shoulda/context/context.rb:76

I believe this issue may have been introduced in minitest/minitest#1017.
