[FIX] board: open kanban card from dashboard

The Kanban view has been refactored recently, and the communication mechanism
between the view and its cards changed. The cards now communicate with the
view by triggering_up custom events.

The code in dashboard overrides the function open_record of the Kanban view to
allowing opening a record by clicking on a card directly from the dashboard.
Unfortunately, this code hasn't been adapted after the Kanban refactoring.
