Lister with JS paginator should still complete the initialization when scrolled (init/setOrder should not matter if called first or last)

[mvorisek]

code to reproduce:

$crud = Crud::addTo($app);
$crud->setModel(new Country($app->db));
$crud->addJsPaginatorInContainer(20, 500 /* $containerHeight */);
$this->table->onRowClick(...);

the problem is addJsPaginatorInContainer terminates [1] the rendering and onRowClick is completely ignored when called from dynamic scroll AJAX

this problem poped out with #1932 fix where we unregister all events from original/non-AJAX load
