wrong client_id in section 6.2

[Nikos Fotiou]

The request object example in section 6.2 includes the following client_id

"client_id": "https://client.example.org/post",

But the Request URI example that follows includes a different client_id

client_id=https%3A%2F%2Fclient.example.org%2Fcb

I believe that these two ids should be the same.

Need to fix.
