Improve logging about glewlwyd

[babelouest]

I agree, an optional property should be optional indeed. I've added this recently after a feature request but I don't need it myself, so I didn't fully tested all the use cases, and the default configuration is confusing.

In you case, if you don't need this feature, i.e. you don't need an additional key/value in your access tokens, you can comment the line where the additional_property_name value is set, or leave the value blank (""), this will disable the additional property in Glewlwyd.

Concerning the log level, it's by design that I don't leave DEBUG messages in the releases, I prefer having explicit error messages that will help me pointing out where the problem is, without fllooding the user with unncessary debug messages.

In your case, the response body was enough to figure out how to fix, I'll fix the front-end though, so the error 400 can't even be reached. But to me that's another reason not to let cryptic debug messages in the application ;)

Although, thanks for the compliment, it's very much appreciated :)
