Add test coverage for SLF4J and Log4J loggers

Confirmation

• I have checked for similar issues.

Problem

There is currently no tests covering the ChameleonSlf4jLogger and ChameleonLog4jLogger implementations.

Suggested solution

It would be a good idea to add test coverage for our logger implementations, allowing us to validate that all method invocations are handled and forwarded to the underlying logger correctly.
