[FIX] mail: enable seen feature only on direct chats

Revision on https://github.com/odoo/odoo/commit/844fb2b51ea7cfa557b19466c0a53dde19433e7a

There were performance issue with the seen feature in multi-
user channnels, therefore it has been disabled for them.
As a result, only direct chats have this feature.
