Simple Quartz example does not output log message as shown in the readme

There was a change introduced with apache-servicemix-4.4.0-fuse-00-61 in which the format of the output changed.

The readme.txt that accompanies the Quartz example reads as follows:

"When the quartz.xml file is copied to the deploy directory, it sends
messages to the log. You can view the log entries by typing the
following command in the ServiceMix console:

log:display

You should see an entry similar to the following:

14:15:51,202 | INFO | x-camel-thread-4 | test

The body of the message is no longer readable as it is a StreamSource. The current output of the example displays as follows:

12:41:42,765 | INFO | rovider-thread-2 | test | ? ? | 85 - org.apache.camel.camel-core - 2.8.0.fuse-01-06 | Exchange[ExchangePattern:InOnly, BodyType:org.apache.servicemix.nmr.core.util.StringSource, Body:[Body is instance of java.xml.transform.StreamSource]]

This behavior appears to have changed with org.apache.camel.camel-core - 2.7.3.fuse-00-61

The example quartz.xml should be updated with either of the below options to produce the output that matches the readme.

1)

<camel:camelContext>
<camel:route streamCache="true">
<camel:from uri="jbi:endpoint:http://servicemix.apache.org/examples/camel/receiver/endpoint" />
<camel:to uri="log:test?showStreams=true" />
</camel:route>
</camel:camelContext>

2)

<camel:camelContext>
<camel:route>
<camel:from uri="jbi:endpoint:http://servicemix.apache.org/examples/camel/receiver/endpoint" />
<camel:convertBodyTo type="String"/>
<camel:to uri="log:test" />
</camel:route>
</camel:camelContext>

An alternative would be to change the readme to reflect the output with the examples current configuration.
