Logging race condition in tests

[rossjones]

When checking tests for race conditions (e.g. cmd/cli/serve/serve_test.go) it highlights some race conditions in our tests with many referencing the logging library.

      .../pkg/logger/logger.go:86 +0x3c

There appears to be an issue with how we set up logs in tests, and in particular the logging for Kubo seems to trigger it.

The zerolog issue at rs/zerolog#242 suggests that we're using it incorrectly and we should find some other way of not triggering the race conditions in tests.
