/studio/templates/ can be accessed without session id

[MaelAudren]

The documentation https://try.activeeon.com/rest/doc/#-1481893167 shows that the request needs a session id for the request.

GET and POST request both return a 200 code when executing the request without sessionid instead of returning a Error 501 Unauthorized.

Test : https://try.activeeon.com/studio/templates/ Accessing to the upper url with a browser return the list of the templates.

We could remove this endpoint to directly relies on the Catalog soon, for a new feature which is ongoing.
