Sample to reproduce the issue

Steps to reproduce

1. docker-compose up -d
2. ./gradlew build
3. java -jar build/libs/sleuth-rabbit-0.0.1-SNAPSHOT.jar

Expected that all send messages have sample state 0, because of SamplerFunction<MessagingRequest> returning false in all cases. However, the first ten messages have the state 1.
