♻️(backend) refactor list view to allow filtering other views

the "filter_queryset" method is called in the middle of the
"get_object" method. We use the "get_object" in actions like
"children", "tree", etc. which start by calling "get_object"
but return lists of documents.

We would like to apply filters to these views but the it didn't
work because the "get_object" method was also impacted by the
filters...

In a future PR, we should take control of the "get_object" method
and decouple all this. We need a quick solution to allow releasing
the hierchical documents feature in the frontend.
