Specify which window is creating exceptions in portals WPTs

promise_rejects_dom and promise_rejects_js are strict about which
constructor is being used for the exception. In portals WPTs, we
frequently open a new window to run the test as we can't destroy the
context the test harness is running in. We now specify which window is
producing the expected errors.
