CorrelationPropertiesExpressionEvaluator is a default implementation used for
getting the Correlation information from a message. This object is only used when
getting a specific property to be set on the message. When reading the property
the getProperty(...) or the direct property accessor will be used i.e.
message.getCorrelationId() or
message.getProperty(MuleProperties.MULE_CORRELATION_ID_PROPERTY)
