Tracker update error

following picture is the reault of the postman:

Have you tried with json.dumps?

In the lasted version somehow the endpoint

PUT /conversations/(str: sender_id)/tracker

was moved to

PUT /conversations/(str: sender_id)/tracker/events.

This change is not documented, I figured it out myself.

@derdanielb would you mind submitting a PR to the HTTP API docs to update that?
