Wiss update event

PR for help

There are 2 fixme in EventEditForm.jsx

First one, I'm not being able to retrieve the id that is passed from Events.jsx (in the tablesorter)

Second one, I can't retrieve from the backend the event. The call is made, and if I try outputting in the backend the event, it works, I just can't pass it to the frontend... Halp

like I said earlier, in the frontend you're expecting to receive `{event: event}` which you don't do. I think the backend is correct, you should fix the frontend to match the signature here
