Helpdesk tests were updated to match recent changes in how empty grouped kanban views are handled. This helps ensure the Helpdesk interface remains reliable when ticket groups have no records.

This commit adapts a test to changes made in https://github.com/odoo/odoo/pull/208851

task-4762308

Add a tracking flag to the payments state to be logged into the chatter.
