Week4 finish reset password

That makes sense.  I should have realized that.  This works fine, but can be confusing to other developers.  If it was my code, I would do this:

```
- if @user != current_user
  - if current_user.follows?(@user)
    =link_to "Unfollow", followship_path(current_user.get_followship(@user)), class: "btn btn-default", method: :delete
  - else
    =link_to "Follow", followships_path(followee_id: @user.id), class: "btn btn-default", method: :post
```
