    Fix a pagination logic bug in test_bug_1689692

    This test attempts to list all instances, then list them again with the
    first instance as the marker and ensure that the remaining instances
    are returned in the page. Now that we are doing queries to cells in
    parallel, consecutive unsorted list queries can return things in
    different orders as the cells may reply at different times. The fix
    in this patch is to ask for results to be sorted, which is the only way
    it makes sense. It worked before purely because we were always scanning
    the cells linearly and in the same order.
