Bug Report

Problematic Behavior
On organization page, the way to build courses and persons pagination links is weird. Actually, useless query parameters are conserved in pagination links. It has mainly one drawbacks has each organization page with a proper set of query parameter has a dedicated cache key...

Expected behavior/code
Pagination links should only be build with useful query parameters (courses_page & page). All others should be ignored.
