    prop224: Fix one last instance of get_time_period_num() with now.
    
    When purging last HSDir requests, we used time(NULL) for computing the
    service blinded key but in all other places in our codebase we actually
    use the consensus times. That can cause wrong behavior if the consensus
    is in a different time period than time(NULL).
    
    This commit is required for proper purging of HSDir requests.
