Description

The camel xquery support no longer works correctly as of 2.18.x

I identified two main issues so far:

1. A java.lang.NullPointerException is thrown when exchange contains any null headers or properties:

   java.lang.NullPointerException: External object cannot wrap a Java null
   	at net.sf.saxon.value.ObjectValue.<init>(ObjectValue.java:55)
   	at org.apache.camel.component.xquery.XQueryBuilder.addParameters(XQueryBuilder.java:640)
   

2. An error in execution whenever a header or a property are referenced in the xquery as an external variable:

   java.lang.AssertionError: Unknown event
   	at net.sf.saxon.evpull.ComplexContentProcessor.advance(ComplexContentProcessor.java:198)
   

Attached is a maven project with junit test illustrating the issues.
