Use RaisesOnDoubleResult after CachesReturnValue

[marian13]

• No need to check whether a service has a double result when its result is already cached.

  # before
  middlewares :result do
    # ...
    use Plugins::Common::CachesReturnValue::Middleware
    # ...
    use Plugins::Service::RaisesOnDoubleResult::Middleware
    # ...
  end

  # after
  middlewares :result do
    # ...
    use Plugins::Service::RaisesOnDoubleResult::Middleware
    # ...
    use Plugins::Common::CachesReturnValue::Middleware
    # ...
  end

Complexity: Low

Hard Requirements:

• A comprehensive test suite.
