[COOP] reporting: reenable OriginTrial tests.

Reenable two test:
-CoopReportingOriginTrialBrowserTest.AccessReportingWithToken
-CoopReportingOriginTrialBrowserTest.CoopStateWithToken

They were disabled by:
https://chromium-review.googlesource.com/c/chromium/src/+/2365362

We think this might be fixed by:
https://chromium-review.googlesource.com/c/chromium/src/+/2366778

Feel free to immediately revert this patch if the two tests start to
fail. We will also monitor them today.
