The problem with this is the email went out already, but in Odoo, it keeps as `outgoing`, causing multiple emails went out for same record in Odoo. This commit adds a `flush_recordset` before to send the email, if there is another process trying to update the same record, it will be blocked and it must wait to sending email process finishes. The mail record will be updated as `sent`.
