Make hashcode test really useful

[Vlatombe]

The hashcode test is not testing much really. It is more efficient to check all fields and check whether they change the hashcode.

In the process, I saw that one of the fields (tokenAuthMethods) was missing from the hashCode method computation.

Testing done
