Public bug reported: Neutron returns reference to next and previous in list APIs "Only when any item is returned". However the client implementation in neutron-tempest-plugin always assumes these refs are present. This results in uexpected failures in some api call.
For example in https://zuul.opendev.org/t/openstack/build/0208cd2fa5ac45199ee047f796ab1eb6 the following error is found. ``` ft1.6: neutron_tempest_plugin.api.test_subnets.SubnetsSearchCriteriaTest.test_list_pagination_with_href_links[id-351183ef-6ed9-4d71-a9f2-a5ac049bd7ea]testtools.testresult.real._StringException: pythonlogging:'': {{{ ...
