UrlEncoded Path Parameters received correctly in Fuse but sent out decoded

Issue

• In completely "vanilla" FuseESB (both 7.0.2 and 7.1) if you pass in a URL containing query parameters with values containing URI encoded characters, the characters become double encoded as they pass through the Camel route.

For example if the following route is used:

<route id="JettyTestRouteA">
    <from uri="jetty:http://localhost:8281/jettyTestRouteA?matchOnUriPrefix=true"/>
    <log message="Using JettyTestRouteA route: CamelHttpPath=[${header.CamelHttpPath}], CamelHttpUri=[${header.CamelHttpUri}]"/>
    <to uri="jetty:http://localhost:8282/jettyTestRouteB?bridgeEndpoint=true&amp;throwExceptionOnFailure=false"/>
</route>
<route id="JettyTestRouteB">
    <from uri="jetty:http://localhost:8282/jettyTestRouteB?matchOnUriPrefix=true"/>
    <log message="Using JettyTestRouteB route: CamelHttpPath=[${header.CamelHttpPath}], CamelHttpUri=[${header.CamelHttpUri}]"/>
</route>

If this route is then invoked using the following URL:

http://localhost:8281/jettyTestRouteA/path?param1=%2B447777111222

The parameter param1 becomes improperly encoded to %252B447777111222:
