JAX-WS: Duplicated namespace in outbound request

[BerksanAtes]

Describe the bug
Default namespace was added to the outbound request message. This action duplicated same namespace causing Web Service failure.

Sample soap envelope with duplicated default namespace

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
	<SOAP-ENV:Header/>
	<SOAP-ENV:Body>
		<ns0:getAddress xmlns="http://objects.get.address.io/" xmlns:ns0="http://objects.get.address.io/">
			<Address xmlns="">
				<streetNum>101</streetNum>
				<streetName>Main St.</streetName>
				<city>Some City</city>
				<state>Texas</state>
				<zip>78598</zip>
			</Address>
		</ns0:getAddress>
	</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Steps to Reproduce
Using SAAJ version 1.4.0 the sample code will create the issue

           MessageFactory mf = MessageFactory.newInstance(protocol);
           SOAPMessage request = mf.createMessage();
            SOAPPart part = request.getSOAPPart();
            SOAPEnvelope envelope = part.getEnvelope();
            SOAPBody body = envelope.getBody();

            SOAPFactory SOAP_FACTORY = SOAPFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);
            SOAPElement getAddressElement = SOAP_FACTORY.createElement("getAddress", "ns0",
                    "http://objects.get.address.io/");

            SOAPElement addressElement = SOAP_FACTORY.createElement("Address", null, "");

            addressElement.addChildElement("streetNum").addTextNode("101");
            addressElement.addChildElement("streetName").addTextNode("Main St.");
            addressElement.addChildElement("city").addTextNode("Some City");
            addressElement.addChildElement("state").addTextNode("Texas");
            addressElement.addChildElement("zip").addTextNode("78598");

            getAddressElement.addChildElement(addressElement);

            body.addChildElement(getAddressElement);

            ByteArrayOutputStream byteOut = new ByteArrayOutputStream();
            request.writeTo(byteOut);
            String requestString = new String(byteOut.toByteArray());
            out.write(requestString);

Expected behavior
Default namespace should be added once
