    Fix race in _test_live_migration_force_complete

    The number of versioned notifications received in the
    _test_live_migration_force_complete method is racey since
    by the time we check we could have entered _post_live_migration
    and received up to four more notifications. This change softens
    the assertion to go from "equal to 6" to "at least 6".
