When the logger expression contains a pipe (|) in a Groovy evaluator it fails, logging the content of the expression twice.

Steps to reproduce:
1. Create a Mule application with the attached configuration
2. Call the inbound endpoint
3. Look at the logs, it should log the expression twice: INFO (LoggerMessageProcessor.java:100) -Hello|Hi|Hello|Hi
