utils.py initialize_server_request should have an "and" instead of "or"
When using the django-oauth-plus on a django project with the test Client and django-rest-framework with OAuth I get an error on POST-requests with content-type application/json ("Invalid signature. [..]").
If I change the "or" between the check for content-type form-urlencoded and server name testerver to an "and" my tests pass. It seems strange to me that all POST requests that are either form-urlencoded OR to testerver should apply what I understand as a hack to deal with form-urlencoded POSTS on django testserver.
Is there some reason I don't understand why there should be an "or", or should this be changed to an "and"?
