The system tray has been simplified:
- only one clickable area per activity group
- by default, a click on an activity group open the list view, except for some
model (ex.: journal entries, project, task, documents where the activity view
is opened). This can be defined per model using the _systray_view attribute on
the model.
- the clock icon providing access to the activity view has been removed. As it
is the only action, we also remove "actions" returned by systray_get_activities
in res_users.
- the KPIs are no longer clickable
The tests have been updated (for example, because we open the list view instead
of the kanban view) and one removed "activity menu widget: activity view icon"
as we only have one clickable area now and no more icons.
