Fix undefined method error when example_block_node is nil

Thanks for the pull request. However I think this is not a fundamental solution. Could you provide a reproducible example code?

hi
I examined the cause, and I thought this was not a fundamental solution,too.

my bad spec example

describe ModelA do
  before { @model_a = ModelA.new }
  subject { @model_a }

  it { should respond_to(:id) }
  it { should respond_to(:has_many_models) }

  describe "relation" do
    let(:model_b) { FactoryGirl.create :model_b }
    before do
      model_b.relation(@model_a)
    end
    its(:has_many_models) { should have(1).items } # error here
  end
end
