[13.x] Fix skipping consent prompt

[hafezdivandari]

Fixes #899

As stated on the docs, we skip the auth prompt if the user previously authorized access to the consuming application for the requested scopes. However, the current implementation checks the scopes of the latest valid token only, not all the previously granted scopes.

This PR does:

• Fix implementation of skipping authorization screen.
• Pass user and scopes to Client::skipsAuthorization() method.
