Log messages are displayed twice

Make a new V2 function app in VS, pick http trigger, run the app and trigger the function. You'll get the following output:

info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
      Request starting HTTP/1.1 GET http://localhost:7071/api/Function1
info: Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[1]
      Authorization was successful.

Note that the message C# HTTP trigger function processed a request appears twice, once with a timestamp and once without.

Same as Azure/azure-functions-host#3432
