Similar to `flush()`, other methods those use `getClient` (in FTPTransfer)
or `getChannel` (in SFTPTransfer) should pass incoming FlowFile in order to
evaluate EL properly.
[NIFI-3590](https://issues.apache.org/jira/browse/NIFI-3590) is essentially the
same to NIFI-3281 which is caused by not passing FlowFile.
Do we want to address it, too? Ideally, the codes `getClient(null)` and
`getChannel(null)` should be removed completely.
