[tests] Fix ReactDOMAttribute-test (facebook#35654)

In facebook#35646 I thought there was a
bug in trusted types, but the bug is in jsdom.

For trusted types we still want to check the coersion and throw for a
good dev warning, but prod will also throw becuase the browser will
implicitly coerce to a string. This ensures there's no behavior
difference between dev and prod.

So the right fix is to add in the JSDOM hack that's used in
`ReactDOMSelect-test.js`.
