makePromise().then(thenHandler, catchHandler) is incorrectly considered correct by the always-catch plugin when allowThen: true is specified.

While the catchHandler will handle a rejection of the Promise returned by makePromise(), it will not handle any rejection that happens in the thenHandler; it needs to be handled by its own catch handler, which could be a .then(null /* | undefined */, catchHandler) according to allowThen: true.
