[bindings] Move additional score params from `&()` to `Default`

In 26c1639ab69d6780c97a118f09e42cb42304088a (and later in
50c55dcf32466e3ccf17acea50697fc664950deb) we switched to using
`Default::default()` to initialize `()` for scoring parameters in
tests. A number of `()`s slipped back in recently, which we replace
here.
