Yahcli account create returns `INVALID_NODE_ACCOUNT`

DevOps attempted to run an account create command in mainnet with Yahcli, but received an `INVALID_NODE_ACCOUNT` error with version `0.7.9`. They tried the same command with version `0.3.0`, which was successful. We need to figure out why the first one didn't work.

Yahcli version that didn't work: `0.7.9`
Yahcli version that did work: `0.3.0`

Command run:
```
docker run -it -v $(pwd):/launch gcr.io/hedera-registry/yahcli:0.7.9 --fixed-fee 100000000 --node-account 4 --network mainnet -p 950 accounts create -a 100
```

Stack trace (from version 0.7.9):

Reproduce the supplied Docker command, then trace the account-create path through CreateCommand.java, HapiTxnOp.java, and the precheck handling shown in the stack trace. Compare the relevant behavior between Yahcli 0.7.9 and 0.3.0; done means identifying why node account 4 is rejected in the newer version and documenting or correcting the regression.
