[miherlosev]

Run a simple test 50 times.

fixture `TypeText speed up test suite`
    .page('https://devexpress.github.io/testcafe/example/');

for (let i = 0; i < 50; i++) {
    test('test', async t => {
        await t.typeText('#developer-name', 'Peter Parker');
    });
}

Execution time (from fastest):

• improved proxyless mode (this PR) - 41s.
• regular mode - 42s.
• current proxyless mode (master) - 51s.
