Previously the only way to get a null logger was to define the logger as null explictly in the driver, which would replace the no-op logger at NullLogger.Instance instead we check if it is null there and ignore the null parameter. half of the code also then wraps the logger in a prefix logger so would end up not being null, but still no-oping
