[victoralmau]

FWP from 16.0: https://github.com/OCA/server-tools/pull/3025

Avoid sending tracking o2m emails if you are subscribed to notes

Example use case:

• Enable custom tracking in project.project
• Activate the task_ids field as custom tracking
• Create a project and assign it to a user (different from ours) and make it a note follower
• Create a task in the project
• The project message of the task tracking task will not be sent to the note followers
