In the Employees app, when using the department kanban view and clicking on the
Time Off Requests or Allocation Requests, it leads to a tree view but the department
from which the user comes from is not part of the filters.
This commit adds the department in the filters of the tree view.
Due to the search panel being present in the tree view, the department filter is removed from the list of
filters to avoid a duplication of the filters in the search panel.
