HTTP client error log after successful request

[Ksisu]

30 seconds after successful login with GitHub provider, got some ERROR log. I think the root problem is somewhere in the AkkaHttpWrapper because there is two calls and in the log the akkaSources are:

• tutelar-system/Pool(shared->https://github.com:443)
• tutelar-system/Pool(shared->https://api.github.com:443)

akka/akka-http#2728
The info logs are normal. And the errors can be fixed by config:

akka {
  http {
    client {
      idle-timeout = 120 s
    }
    host-connection-pool {
      idle-timeout = 150 s
    }
  }
}
(the client idle timeout have to smaller then host idle timeout)
