[FIX] crm: New / opportunity in the dashboard opens an opp form

Up to now, it opened the lead form view instead
of the opportunity form view.

Most-likely, a new / lead should be added to
the dashboard in addition to the new opp,
as this is the case with the view lead/opportunity
but it doesn't seem it was expected up to now
so I leave it like it is.
