test: test about:blank against invalid WHATWG URL

[joyeecheung]

If failure is true, parsing about:blank against base
must give failure. This tests that the logic for converting
base URLs into strings properly fails the whole parsing
algorithm if the base URL cannot be parsed.

Fixes: #20720

Checklist

@apapirovski Thank you for starting the CI. The two failures on vs2017/win2016 seems irrelevant.
