One of the tests also had an error: 

Test bug: unrecognized DOMException code "() => { const request = new PaymentRequest(defaultMethods, details, { requestShipping: true, }); }" passed to assert_throws()

Will fix it too

Forgot to write the name of the test that has an error: If there are any duplicate shipping option ids, and shipping is requested, then throw a TypeError

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/5d2f94cd0a521244001f23e858e199ee39b19edb

[Payments] Blink: Throw TypeError if 2 shipping option have same id.

Relevant section of the spec:
https://www.w3.org/TR/payment-request/#constructor

"If seenIDs contains option.id, then throw a TypeError.
 Optionally, inform the developer that shipping option
 IDs must be unique."

Since those were the last 2 Failures for the payment-request-constructor
.https.txt, removing the associates expected file.
