Replace `WebDriverWait`

[cleborys]

by something that gives a more meaningful error message than TimeoutException.

I don't want to put every WebDriverWait in a try block,
rather have a wait_for_element_by_id(driver, id) function or even
driver.wait_for_element_by_id(id) that throws UnexpectedLayoutError`

This is partly solved by introducing waitUntil for retries.
