I’m renaming all instances of `use_transcational_fixtures` to `use_transactional_tests` and “transactional fixtures” to “transactional tests”. I’m deprecating `use_transactional_fixtures=`. So anyone who is explicitly setting this will get a warning telling them to use `use_transactional_tests=` instead. I’m maintaining backwards compatibility—both forms will work. `use_transactional_tests` will check to see if `use_transactional_fixtures` is set and use that, otherwise it will use itself. But because `use_transactional_tests` is a class attribute (created with `class_attribute`) this requires a little bit of hoop jumping. The writer method that `class_attribute` generates defines a new reader method that return the value being set. Which means we can’t set the default of `true` using `use_transactional_tests=` as was done previously because that won’t take into account anyone using `use_transactional_fixtures`. Instead I defined the reader method manually and it checks `use_transactional_fixtures`. If it was set then it should be used, otherwise it should return the default, which is `true`. If someone uses `use_transactional_tests=` then it will overwrite the backwards-compatible method with whatever they set.
