erreur when reply with `HttpResponse` with circuit breaker

[deblockt]

When we use a circuit breaker with web-client we have this exception:

15:49:40.631 [vert.x-eventloop-thread-6] 83171574-ac36-4212-abc9-f51656734a2a ERROR io.vertx.core.impl.ContextImpl - Unhandled exception

The code is the following:

breaker.executeCommandFuture[HttpResponse[Buffer]](future => {
    performSomeHttpRequest() onComplete {
      case Success(httpResult) => future.complete(httpResult)
      case Failure(error) => future.fail(error)
    }
})

To fix that, we have encapsulated the HttpResource on a custom class Wrapper.

It seem that this failure occurs because HttpResponse.apply need an implicit type scala.reflect.runtime.universe.TypeTag, and the method toScala doesn't support that.
