Check if during update all content the ServicingNodeIndexer queryHandlerContext is fine with the queryHandlerContext.getNamespaceRegistry().getPrefix

Specifically, test if after an update all content, with a changed namespace that this works:

String primaryNodeName = queryHandlerContext.getNamespaceRegistry().getPrefix(value.getQName().getNamespaceURI()) + ":" + value.getQName().getLocalName();
