        This test tests multiple behaviours and edge cases. First off, when
        there is a project (with AAs) associated to an MO, the analytic entries should only
        be generated when the MO's components are consumed/reserved (i.e.
        picked). Second, when changing the produced quantity in a confirmed MO,
        it should appropriately adjust the amount of picked components. Third,
        analytic entries should at all times reflect the current situation, and
        thus must be regenerated every time there's a change in components'
        picked status.
