test_invalid_auth_url shouldn't hit arbitrary web server

[Mark Washenberger]

Running test on a box that attempts to redirect arbitrary urls breaks glance functional tests.

======================================================================
ERROR: test_invalid_auth_url (glance.tests.unit.test_auth.TestKeystoneAuthPlugin)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/var/lib/jenkins/custom_workspaces/glance/glance/tests/unit/test_auth.py", line 178, in test_invalid_auth_url
    plugin.authenticate()

    _authenticate(auth_url)

    raise Exception(_('Unexpected response: %s') % resp.status)
Exception: Unexpected response: 302

This is just silly! The test shouldn't actually be hitting http://localhost/badauthurl :-)
