Title: Allow policies and scopes to be injected into controllers.

In controller specs instead of relying on Pundit to instantiate the correct
policy object allow it to be injected into the controller. More often than not
a double is used in controller specs which means the policy cannot be
inferred. This also allows us to double the policy to ensure that on a unit
level the rights methods are being called on callaborators.

class PostsController < ApplicationController
attr_writer :post
helper_method :post

def create
authorize post

post.save
respond_with post
end

private

def post
@post ||= Post.new post_attributes
end
end

describe PagesController do
let(:policy) { double 'SomePolicy', create?: true }

before do
controller.policy = policy
end

it 'delegates authorization to policy' do
expect(policy).to have_received(:create?)
end
end

Add spec for injecting policy.

Use `or` instead of ternary operator.

Allow policy_scope to be injected for controller tests.
