ui: Fix non admin logouts (apache#8065)

If a user (non-admin) logs out from a session, then login page is not loading completely. Few starter APIs like listIds are failing and showing unauthorised access notification in Login Page. Also if SAML is enabled, it is not getting enabled since the corresponding API are failed. User needs to refresh the browser to get it back.
