adb-tests ExtensionTest failure for wrong element

//this fixes missing currencyElement from SimpleExtensionTest::testPaymentAmountElementParse:

//create the currency element
OMElement subElement = factory.createOMElement(new QName("http://apache.org/axis2/schema/extension", "currency"));

//add subElement to element
element.addChild(subElement);

//now create the XMLStreamReader from element (with subelement currency)
XMLStreamReader reader=element.getXMLStreamReader();
