Currently, portal followers of a project and its tasks are removed when
the project visibility is changed to something else than portal.
=> We want to keep the behavior, but only when changing the visibility
from portal to something else.
When the project visibility is changed to portal, we currently add
its customer to its followers.
=> In that case, we also want to add the customer of the tasks to the
followers of the corresponding task.
When the customer of a project in portal visibility is changed, the
new customer is added to the followers of the project.
=> We want to remove this behavior.
When a project is created with a customer and the portal visibility,
the customer is added to the followers of the project.
=> We want to remove this behavior to avoid mistakenly showing a project
that is not ready yet to the customer.
This commit implements those changes, and also adds a warning when
changing the visibility of the project if that change will automatically
add/remove followers to the project and its tasks.
