fetch methods requires argument parameters to be an array when token is passed in the URI

[thesailorbreton]

It seems that in some cases when the query is POST, you want to have the access_token to be passed in the URI and you want the parameters to be a simple variable (like an XML content for example) and not an array.

I am unsure that this is a bug (I am not an Oauth2 specialist) but Pierrick asked me to log it.
