Core: The description of exp claim for client authentication contains the word "ID Token" - it should be just a token

[Tatsuo Kudo]

"the token" is more appropriate than "the ID Token" in the following description on client authentication.

http://openid.net/specs/openid-connect-core-1_0.html#ClientAuthentication

exp REQUIRED. Expiration time on or after which the ID Token MUST NOT be accepted for processing.

I believe this is the same as Issue #982

[Michael Jones]

I'll keep this open until issue #982 is also resolved.
