"tx_missing_posting_auth" when setting "allow_votes" to false in "comment_option"

[wehmoen]

Expected behavior

When I set allow_votes to false in the comment_options I expect that it is no longer possible to vote on a comment.

Actual behavior

Right now everytime you try this you will receive tx_missing_posting_auth. For a full stack trace check this link: https://pastebin.com/RUzxZABX

How to reproduce

I wrote a small script which uses busys test account guest123 to demonstrate this bug:

let steem = require("steem");
 
let username = 'guest123';
let postingWif = '5JRaypasxMx1L97ZUX7YuC5Psb5EAbF821kkAGtBj7xCJFQcbLg';
let permlink = new Date().toISOString().replace(/[^a-zA-Z0-9]+/g, '').toLowerCase();
 
let commentData = {
    parent_author: '',
    parent_permlink: 'test',
    author: username,
    permlink: permlink,
    title: "test",
    body: "this is a test",
    json_metadata: JSON.stringify({})
};
 
const comment = ['comment', commentData]
 
const commentOptionsData = {
    author: username,
    permlink: permlink,
    allow_votes: false,
    max_accepted_payout: '1000000.000 SBD',
    percent_steem_dollars: 10000,
    allow_curation_rewards: false,
    extensions: []
};
const commentOptions = ['comment_options', commentOptionsData];
 
steem.broadcast.send({operations: [comment, commentOptions]}, {posting: postingWif}, (err, result) => {
    console.log(JSON.stringify(err), result);
});

Environment information

I tested it with the latest version of nodeJS on my Mac (v10.14) and on one of my servers running Ubuntu 16.04
