fixed ocs function for Group Folders app routes (#279)

Fixes #277 .

Changes proposed in this pull request:

* we use `request.headers["Accept"] = "application/json"` in addition of
appending `format=json` to the query url(look below why).
* changed ocs_regexp to `r"/ocs/v[12]\.php/|/apps/groupfolders/"` until
groupfolder app will fix it.
