Note about Token Store for Claims Mapping to work

[Nicolai Søborg (nis-spiir)]

If the token store is disabled (non-default) then the AAD ID token (X-MS-TOKEN-AAD-ID-TOKEN) is not sent and at least the big Microsoft.Identity.Web SDK can't map the weird X-MS-CLIENT-PRINCIPAL (non-JWT) to a ClaimsPrincipal
