[FIX] hr: Open department employees with searchpanel

From the department kanban view,
when clicking on the "Employees" button of a department,
it shows all employee regardless of their department.

This is a consequence of the back2basics commit 9a0fedf
which removed the department filter and added a
search panel instead.

This commit changes the search default filter
to a default filter for the searchpanel.
