OIDC: Fixed incorrect detection of group detail population

An empty (but valid formed) groups list provided via the OIDC ID token
would be considered as a lacking detail, and therefore trigger a lookup
to the userinfo endpoint in an attempt to get that information.

This fixes this to properly distinguish between not-provided and empty
state, to avoid userinfo where provided as valid but empty.

Includes test to cover.
