Adding through relationship to Wiki and User models

John -

In reading the exercise doc, this part did not get added before so I am correcting it. The Wiki and User models needed a 'through' piece. I think I did this correctly, let me know.

The naming is a bit weird here, it doesn't make much sense to have user.users collection. What you want are the wikis. So try this: has_many :wikis_i_am_collaborating_on, through: :collaborations, class_name: 'Wiki'
