Fix broken test on newer Node.js versions #862

Closed geofft closed 2 years ago

geofft commented 2 years ago

This test has always been broken, but in older versions of Node, it didn't report a failure, because unhandled promise rejections didn't cause a test failure:

Since Node.js v15 this causes an actual test failure. GitHub CI uses Node.js v16.
