Feature: Hide route single point geometry on view when there is a track

I'm not sure how #1994 has actually been implemented, but I've hit the same issue just yesterday on a *route*, [this one](https://www.camptocamp.org/routes/50900/fr/grand-capelet-tour-et-sommet) (#1994 was about outings)
I ended up "hiding" the point behind a lake, because the ideal place for it with the usual guidance (close to main summit) was already "full".

I really don't see the point of showing the point in this case ;-)
