missing default Logger configuration

[mirkof]

Hello,

We updated to Play 2.5 with Scaldi. We are using default play.api.Logger.

But I've notices that there is no Logger configuration...
https://www.playframework.com/documentation/2.5.x/SettingsLogger#Using-a-custom-application-loader

Or maybe I'm wrong and this unrelated. :/

And this is the error that we got when we tried to run the app in production:

This was the actual problem, not Scaldi.

Sorry and keep up the good work! :)
