[ChromeDriver] Stop using --ignore-certificate-errors

ChromeDriver was passing --ignore-certificate-errors switch to Chrome,
regardless of whether user wants to ignore certificate errors or not.
Fixing by stop passing this flag to Chrome, and relying on using
Security.setIgnoreCertificateErrors command when user wants to ignore
certificate errors.
