…xchange Exchanging an opaque access token (an encrypted tokenID:subject string) panicked, because getTokenIDAndClaims returns nil claims with ok true and the caller dereferenced them unconditionally. Skip the dereference when there are no claims and add a test covering that path.

Fixes #704.
Doing a token exchange with an opaque access token panics. When the token is an encrypted tokenID:subject string rather than a JWT, getTokenIDAndClaims returns nil claims with ok true, and GetTokenIDAndSubjectFromToken then dereferences that nil pointer on accessTokenClaims.Claims.
I added a nil guard so opaque tokens come back with empty claims (there are no JWT claims to read in that case), and a test for the opaque path since, as the issue mentions, it wasn't covered before.
