Deal with warning during test collection - rename fake class to avoid false alarm
Deal with warning during test collection - rename fake class to avoid false alarm

A clash between test auto-discovery (find something beginning with "Test") and
a dummy/utility class created for testing the relevant decorator was causing pytest
to raise warning.
Renaming the dummy classes worked - running `pytest bedrock/utils -vv` shows the relevant tests
are run, while the warnings are now gone
