Fix minor recursion in logger

[cdcabrera]

As a maintainer I need to review the potential for a recursion in how logger.ts is subscribing and creating logs

• line 230 in logger.ts
• line 277 in logger.ts

Acceptance criteria

• move to using process.stderr.write instead of the internal log. avoid potential recursive error
• review moving the log formatting into a helper
• discovered during feat(logger): format unknown errors #59
