upsert does not work with associations

[niv]

Just a small bug report: I can't get upsert! to work on associations, like so:

class Parent; ... end
class MyModel
  include BaseModel
  belongs_to :parent
  field :username, String
  field :data, String, unique: { scope: [:parent_id, :username] }
end

MyModel.upsert! parent: @parent, username: "me", data: "test"

It fails on not finding a matching uniqueness validator (because it's looking for :parent_id instead of :parent). As a consequence, if I do

MyModel.upsert! parent_id: @parent.id, username: "me", data: "test"

it works as expected.

(Note that I had to set the uniq validator on :data to look for :parent_id, too, instead of :shard.)

I've fixed this bug.

I've also added the :uniq/unique option on a belongs_to declaration

Tyvm! That was amazingly quick.
