access rules verification does not work without service catalog

[Boris Bobrov]

Steps to reproduce:

1. Create an application credential with an access rule in an identity server
2. Set up a service with keystonemiddleware
3. Set `include_service_catalog = false` for it (because there are issues with the eventlet service)
4. Create a token with the application credential and pass it with a request to the service

Expectation:

Access rules are being verified

Current behavior:

InvalidToken exception is being raised: https://github.com/openstack/keystonemiddleware/blob/f32fcc6623ccaf4c465700c23fa20f66c5c79daf/keystonemiddleware/auth_token/__init__.py#L575
