[FIX] board: clicking on a pivot cell in dashboard

Before this rev., it crashed when the user clicked on a pivot cell
in the dashboard, whereas it should have performed a do_action to
open the records in a list view.

This was due to a leftover event handler (with the handler function
being actually removed) in commit 38dc5c18b.

Issue reported on the saas-12.1 migration pad.
