ASSERTION FAILED: vm->currentThreadIsHoldingAPILock() seen with http/tests/paymentrequest/payment-request-show-method.https.html
https://bugs.webkit.org/show_bug.cgi?id=182591

Reviewed by Youenn Fablet.

Fixes assertion failures in http/tests/paymentrequest/payment-request-show-method.https.html.

DOMPromise::whenSettled() calls the JSC API without first aquiring the API lock, and
r228195 added a call to whenSettled() where the lock is not guaranteed to be already
acquired.

Fix this by creating a JSLockHolder in DOMPromise::whenSettled().

(WebCore::DOMPromise::whenSettled):
