[FIX] board: redirect to form on calendar event click
[FIX] board: redirect to form on calendar event click

Before this commit, when clicking on a event of a pinned calendar view
in the Dashboard app, nothing occurs.

The cursor turns into pointer type when hovering on an event, suggesting
that clicking on it should do something. Kanban and list views redirect
the user to the document's form on click, so a similar behaviour is
expected with calendar view.

This is indeed the case in v11, but not in v10. The reason that it works
in v11 for calendar is that when we click on a record of a pinned views
in dashboard, it performs a do_action to open the form view. In v10, however,
it performs a do_switch_view to the form view. Since there's only one view mode
when we pin something in dashboard, the processing of the click fails silently.
Kanban and list were working because the dashboard app overrides their
handlers functions when loading the views, which wasn't the case with calendar.

This commit solves the issue by also overriding the handler function
of calendar view, so that it performs a do_action to open a form instead
of performing a do_switch_view to the form view.

(Note: pivot and grid views work, because they use do_action)
