XML enrich adds empty namespaces (regression)

[Hooghof]

As a user I want that an XML enrich merges XML bodies without changing the existing namespaces, so that the structure and meaning of the enriched XML-message remain. There is a difference in output between version 4.17.11 and 4.17.12. The empty namespaces xmlns="" are in the output of 4.17.12.
I couldn't find differences in Camel context and the last Camel update was in Fluxygen version 4.17.9.
Seacon hint for this (AI) change: icFactory.setNamespaceAware(true) in XmlHelper.newDocument, see https://dovetailworld.atlassian.net/browse/FG-2643
