[FIX] web: Discard from form view to form view

Clicking on the discard button in a form view whose previous view is
another form view wouldn't do anything.

This is fixed by making the view_manager trigger_up a history_back event
and then the history_back callback will handle cases in which there is
only one view and only one action, which used to be rejected
