The stack we're trying to purge is not purge, so it's not a race with other tests, but within the test itself. It looks like we're trying to purge the stack too quickly after deleting it. Maybe a simple timing issue, but it's weird we've not seen it until now.

    Add a sleep after delete before purging

    heat-manage purge_deleted 0 might not purge deleted stacks which are
    less than a second old, this is a cause of gate failures.
