Describe the issue

./bin/ipc-cli wallet balances returns no error even if using a bad (non-existent) RPC in the config; it just returns 0 balances for every wallet. The expected behaviour would be to return an error.

Repro steps

Run ./bin/ipc-cli wallet balances --subnet XXX --wallet-type evm using a well-formed but bogus RPC endpoint in the ipc-cli config.

@jsoares, fix here: #379 I tested it and seems to work for me, can you confirm?
