Applies the change to the script. The change is always a substring (change_pos, change_pos + change_len) being replaced with a completely different string new_str. This API is a legacy and is obsolete.  @param {Script} script that is being changed @param {Array} change_log a list that collects engineer-readable description of what happened.
