Use double instead of runner in RedisCacheable spec
user
```ruby
require 'spec_helper'

describe RedisCacheable do
  let(:model) { double }

  before do
    model.extend(described_class)
  end

  describe '#cached_attribute' do
    subject { model.cached_attribute(:anything) }

    it 'gets the cache attribute' do
      Gitlab::Redis::SharedState.with do |redis|
