Fix API token unit tests.
Review Request #6213 — Created Aug. 8, 2014 and submitted
Several API tests were failing because the proposed token policies were missing
a "resources" field. I've added this to the tests, and refactored the common
data out so that if we want to make any changes to the policy string, it's only
in one place.
Ran unit tests.
