Has many association does not allow overrides

[cutalion]

This test will fail. Overriding has_many association does not work.

    context 'has_many' do
      before do
        factories.define(:user) do |f|
          # ...
          f.association(:tasks, count: 2)
        end

        factories.define(:task) do |f|
          f.sequence(:title) { |n| "Task #{n}" }
        end
      end

      # ...

      it 'allows overrides' do
        task = factories[:task]
        user = factories[:user, tasks: [task]]

        expect(rom.relations[:tasks].count).to eq 1

        task = rom.relations[:tasks].one
        expect(task[:user_id]).to_not be(nil) # fail
        expect(user.tasks.count).to eq 1 # fail
      end
    end
