    Fix test_update_restricted timeouts due to timestamp resolution

    Updating a stack where the only resource needs replacement but is
    restricted from being replaced is *very* fast. Since the test framework
    relies on seeing a change in the updated_time timestamp, which has only 1s
    resolution, it can easily be missed causing the test to timeout. This adds
    a 1s sleep between updates that have the same expected status to ensure
    that the timestamp changes.
