WS-Addressing module does not set ReferenceParameters for wsa:To

wsa:To ReferenceParameters should be set as per the following standard:
http://www.w3.org/TR/ws-addr-soap/#bindrefp

At present the code which should do such a thing only adds reference parameters for replyto, etc... not wsa:To

axiom_node_t* node = NULL;
axiom_namespace_t* ns = axiom_namespace_create( this->axisEnv, "http://nsuri", "prefix" );
axiom_element_t* element = axiom_element_create( this->axisEnv, NULL, "EleName", ns, &node ); axiom_element_set_text( element, this->axisEnv, "sometext", node );

axis2_endpoint_ref_t* endpointRef = axis2_endpoint_ref_create(
this->axisEnv, this->endpoint.c_str() );
axis2_endpoint_ref_add_ref_param( endpointRef, this->axisEnv, node ); axis2_options_set_to( options, this->axisEnv, endpointRef );
