Re: [html-tests] Fix cross-origin-objects-exceptions.html to expect indices in GetOwnP… (#4662)

It was because we wanted a test that _all_ implementations could pass while implementing the observables that are actually important for security and interop, so they would notice if they ever regressed them.  A problem with wpt is that once you fail an assertion it stops testing everything else in that test, so you lose test coverage unless your tests are written very very carefully.

Looking at the proposed changes now.
