throw option not respected with malformed URLs

[na--]

This script demonstrates the issue:

import { sleep } from "k6";
import http from "k6/http";

export const options = {
    iterations: 10, // just to demonstrate how the sleep() is never reached
    //throw: true, // it's false by default, uncomment to test the different behavior
};

export default function () {
    // this will throw an exception if `throw` is true
    let r = http.get("https://some-wrong-domain.k6.io");
    console.log(r.error_code);

    // this will always throw an exception in the current k6
    r = http.get("https:// test.k6.io");

    // these will never be reached
    console.log(r.error_code);
    sleep(1);
}

And this somewhat connected issue should probably be fixed at the same time: #1199
