Mark McLoughlin 4cd2945740 Fix expired token tests
Fixes bug #983800

The expiration timestamps are expressed in UTC time, so ensure:

 1) The timestamp of the token created by the test is UTC time (i.e.
    utcnow() vs now())

 2) The expiration check in the dummy memcache client properly
    accounts for UTC (i.e. utctimetuple() vs timetuple())
