[REF] mail: remove create_user_id field on activity

As activities are created using the current user there is no need anymore to
have another field to store the activity creator. We can therefore remove
create_user_id and replace its use by the magic create_uid field.

This commit is linked to task ID 1856417 and PR #27619.
