`parent_id` fields are common in many models, and thus default values for those fields are sometimes passed in the context. Because mail.message also has `parent_id` field, it would automatically use the default when an automatic message was being posted. While of course, the parent_id value comes from a different model. This "adoption" by a random "parent message" is unexpected, not desired, and it can even cause a very surprising AccessError if the parent message is not readable by the user. Forcing the `parent_id` value during the creation of an automatic message avoids this confusion. One way to trigger the bug was to use the "subtask" stat button to create a child subtask for a project task (it relies on the parent task ID passed in the context)
