[monero-project/monero] make_multisig error via monero-wallet-rpc: ’empty view keys’ (#4282)

The `multisig_info` parameter is supposed to be an array, so you had to wrap the multisig info around with brackets. Also, you need to specify the `threshold` parameter which is 2 in this case:

curl -X POST http:/localhost:28083/json_rpc -d ‘{«jsonrpc»:»2.0″,»id»:»0″,»method»:»make_multisig»,»params»:{«multisig_info»:[«MultisigV1PzEEyXkePUxKAKR7zmquxufstTxHf5UNyGyztd26dAtb2RWJH6NE7wRADpVaUCUxoq8hCTvTyT9ipZU25SXc8Php7j863hyDJ9VPuGz4dqRHx5J2sFKPfkXpijijwGbUnAJnDjgL3Fphskp3ZQioYt8pJShfobUBf7wkVJUvjuAM4wTx»],»threshold»:2}}’ -H ‘Content-Type: application/json’
