Answering my own question,
After digging around the source code of axis2 i tried setting this in the options of the service client of the stub and it worked, the wsa elements are now removed from the request.
_serviceClient.getOptions().setProperty(org.apache.axis2.addressing.AddressingConstants.DISABLE_ADDRESSING_FOR_OUT_MESSAGES
, Constants.VALUE_TRUE);
