Describe the bug

An offline session continues to be valid when the offline_access scope is removed from the client. The idea is that the refresh operation should return an error if the scope is not assigned to the client anymore. This can confuse administrators, that think removing the scope is enough and they do not remove the sessions associated. Better if we avod this and return an error, saying invalid scope or similar.

Version
