Error when accessing a private competition and not logged in

[Didayolo]

When accessing a private competition through its secret URL and not logged in, we got this:

This is due to this, in views/competitions.py:

        else:
            # if user is not authenticated only filter published/public competitions
            qs = qs.filter(Q(published=True))

This filter is the same for the search bar and for accessing the competition...
