Subusers couldn't be created through the dashboard, because the get call was overwritten with Python magic due to it being the function under the HTTP call.
The get function was therefore split into an "external" and "internal" function, whereas one
can be used by functions without triggering the magic. Since the user object was then returned correctly, json.loads could be removed.
