Activities are quite personal and linked to daily jobs of people using it.
Being notified of all activities is therefore not considered as default
behavior and should be a choice done by users. Subtype linked to logged
activities is now not followed by default anymore. It is still configurable
through subscription widget or parent subscription (project/task for example).
This commit is linked to task ID 1824141.
