        This is a hack to work around problems like CASSANDRA-11811.
    
        The problem happens in commitlog-replaying tests, like the snapshot and CDC
        tests. If we replay the first commitlog that's created, we wind up
        replaying some mutations that initialize system tables, so this function
        advances the node to the next CL by filling up the first one.
