[FIX] web: update breadcrumbs when switching view

To reproduce:
 1. go on list view
 2. open record in form view
 3. come back on list view
 4. switch to kanban
 5. open record in form view
 6. click on breadcrumb

Before this rev. we were back on the list view, and not the kanban view.

This is due to the fact that the breadcrumb was not updated when switching view,
(if a controller was already existing) so the form view control panel breadcrumb
was still referencing the wrong (list) controller.

This bug appeared with the control panel refactoring, which is now managed by
the view itself (and not the action manager as previously).
