users/:user_id/collections scopes do not resolve the correct user's collections

[scytherswings]

The docs page shows how collections are not working properly:

GET /v1/users/af4dfcf0-fe22-5b7a-95fe-9fbe5443d96c/collections?null
200
{
  "links": {
    "self": "http://www.example.com/v1/users/af4dfcf0-fe22-5b7a-95fe-9fbe5443d96c/collections?null?page%5Bnumber%5D=1\u0026page%5Bsize%5D=0",
    "next": "http://www.example.com/v1/users/af4dfcf0-fe22-5b7a-95fe-9fbe5443d96c/collections?null?page%5Bnumber%5D=2\u0026page%5Bsize%5D=0",
    "last": "http://www.example.com/v1/users/af4dfcf0-fe22-5b7a-95fe-9fbe5443d96c/collections?null?page%5Bnumber%5D=0\u0026page%5Bsize%5D=0"
  },
  "data": []
}

User's public collections should be browsable by anyone
