TestCafe should wait until the role initializer is completely finished before saving storages

[AlexKamaev]

You can reproduce the issue with the following code:

import { Role, Selector } from 'testcafe';

const testUser = Role('https://www.instagram.com/accounts/login/', async t => {
    const login = Selector('#react-root > section > main > div > article > div > div:nth-child(1) > div > form > div:nth-child(2) > div > label > input');
    const password = Selector('#react-root > section > main > div > article > div > div:nth-child(1) > div > form > div:nth-child(3) > div > label > input');
    const submit = Selector('#react-root > section > main > div > article > div > div:nth-child(1) > div > form > div:nth-child(4) > button');

    await t.typeText(login, '******');
    await t.typeText(password, '*****');
    await t.click(submit);

    // NOTE: here is a workaround
    // await t.wait(10000);

}, { preserveUrl: true });

fixture `Instagram`
    .page`https://www.instagram.com/`
    .beforeEach(async t => {
        await t.setTestSpeed(0.3);
        await t.useRole(testUser);
    });

test(`test1`, async t => {
    await t.navigateTo('https://www.instagram.com/cristiano/');
    await t.wait(5000);
});

test(`test2`, async t => {
    await t.navigateTo('https://www.instagram.com/leomessi/');
    await t.wait(5000);
});

test(`test3`, async t => {
    await t.navigateTo('https://www.instagram.com/neymarjr/');
    await t.wait(5000);
});

You can uncomment:

    // NOTE: here is a workaround
    // await t.wait(10000);

to make the test work

This example works with the latest version of the testcafe.
