CLOUDSTACK-5996: UI - In project view, the first listRotuers API(without projectid=-1) will return the same objects as the second listRouters API(with projectid=-1), because in project view, all API calls are appended with projectid=[projectID]. Therefore, we only call the second listRouters API(with projectid=-1) in non-project view.
