ESP32: Conditionally log on services to avoid OOM crashes (#1098)

Also removed new line formatting tidy as it requires a bit of memory which might not be available.


* Use suitably scoped char for log newline stripping

* fix formatting

* Better fix for OOM logging crash

* Limit to ESP32 only

* format changes
