Issue Description

Good afternoon,

I am doing a POC about the library running in this way:

java -cp ./target/spring-boot-chaos-poc-0.1.0-SNAPSHOT.jar \
-Dloader.path=chaos-monkey-spring-boot-2.0.0.jar \
org.springframework.boot.loader.PropertiesLauncher \
--spring.profiles.active=chaos-monkey

and if the property: chaos.monkey.watcher.controller: true appear in the configuration, the execution fails.

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

You can test it in the POC. I have isolated the scenario in this branch: https://github.com/jabrena/spring-boot-chaos-poc/tree/feature/codecentric
