Camel event forge Plugin Persistent listener does not process any events

If configured, the route for persistent events is called, but does not process any events:

<route>  
    <from uri="hippoevent:?_persisted=true&amp;_channelName=mylistener&amp;category=workflow&amp;action=publish,depublish" />  
   <to uri="direct:execute-reaction" />
</route>

This is due to the fact that 

org.onehippo.forge.camel.component.hippo.HippoEventConsumer#isConsumable

checks ALL properties of the HippoEventEndpoint against the properties of the endpoint, including the _persisted and _channelName properties. As they both have non-empty values in the route configuration but the event does not have these properties, the event is deemed unprocessable. 

I would suggesst to exclude underscore prefixed Endpoint properties (such as _persisted and _channelName) from being checked in the isConsumable method.

All the best,

Felix
