In REPL LOAD flow, the data copy is done separately for external tables using data locations
dumped in file {@link ReplExternalTables#FILE_NAME}. So, we can skip copying it here.
In case of migrating from managed to external table, the data path won't be listed in this
file and so need to copy data while applying the event.
