* Add some tests for `logger` * Remove deprecated `PrefixedLogger` interface `PrefixedLogger` has been deprecated for some time, so let's remove it now, while we have a major version bump. We can tidy up some of the other logic while we're here. Unfortunately lots of the code still uses `logger.log` which isn't exposed by the `Logger` interface, so we need to keep exposing that where it was before.
