Marking as obsolete pending updates to API tests.

A failing API test was addressed in a separate patch (Bugzilla related to this one).

r=me, but consider my suggestion about the test case.

I think these tests would look better if you asserted EXPECT_FALSE(pcm.calculateAndUpdateSourceUnlinkableToken(serverPublicKeyBase64URL).has_value());

The fact that the return value is an error message (or no-value if successful) isn't obvious from the name, so it looks like we are expecting the calculateAndUpdate to fail.

You're absolutely right. I made the test look like the actually call sites with a local variable errorMessage. Should make it clear.

Thanks for the review!
