Track and fix org.apache.activemq.camel.component.InvokeRequestReplyUsingJmsReplyToHeaderTest failure - works on trunk

org.apache.activemq.camel.component.InvokeRequestReplyUsingJmsReplyToHeaderTest fails. Appears that the replyTo header is not removed so the a reply to a replyTo has the header set and keeps processing... so we get in a loop and the test times out after 20seconds. needs some ivestigation to see what fix has not been merged. This works ok in turnk with 2.10.2
