Speed up integration tests in Rails 5 app

Rails 5 recompiles templates on every request in test env. Fix will be released only in 5.0.2.

Add this lines to test helper to get the performance now (I've got x2 improvement):

class << ActionView::LookupContext::DetailsKey
  def clear
  end
end

Details.
