Flavors throws 500 page instead of graceful 401

[Dolph Mathews]

Branch: stable/diablo

Most pages show a graceful 'Unable to get instance list: 401 Unauthorized' message when the keystone admin token is expired, but Flavors is throwing a 500 page instead: http://paste.openstack.org/show/3508/

To reproduce, you can set your admin token in keystone to expire in the past: UPDATE `token` SET expires='2000-01-01 00:00:00' WHERE id='SOME-TOKEN';

There were lots of other places where this was the case, too.
