[FIX] website_event: fix frontend track edition

When editing a field on a track, a traceback was raised because the
fields website_menu and website_url are not present in the event.track
model.

Now we always use the event.event model and we get the event object id
from the url.
We also set the url as the current one to stay on the same page after
reloading it.
