  1. [BUGFIX LTS] remove bad setFactoryFor call

    This call *attempted* to avoid setting the `INIT_FACTORY` on items
    which did not need it (specifically, it avoided setting it on things
    which were not instantiable), but ultimately failed to do. It was
    ultimately setting the new `FactoryManager` instance as the
    `INIT_FACTORY` value on each instantiable object, which includes
    classes and not just class instances, since objects are only treated as
    non-instantiable when they explicitly specify `instantiate: false`.
    
    The net was a memory leak: the routing service *class* ended up with an
    `INIT_FACTORY` pointing to a `FactoryManager` instance which in turn
    always had a `container` on it, which meant that there was a cycle (the
    container also referenced the service) and thus a leak. This affects
    both tests and FastBoot, where we construct new instances of the
    service whenever we call the `visit` API.
