WebSocket connection handshake does not break by timeout

[denis-maiorov-brightsec]

When the scan is attacking websocket endpoints and websocket server is not responding to initial connect, websocket requests are not timing out

Step to reproduce:

1. Run a scan on target that has ws endpoints that do not respond

const scan = await this.scanFactory.createScan(
  {
    tests: [TestType.SQLI],
    name: TestType.SQLI,
    target: {
      url: '<stuck ws/wss target>'
    }
  }
);

2. Call expect

await scan.expect(async () => {
  const issues = await scan.issues();
  return issues.length > 2;
});

Actual: requests are hanging and expect does not resolve
Expected: requests fail by timeout and expect resolves
