Test curvature drift during position nudging

The test fails, as expected, if you disable sphere normalization by
making `Sphere::normalize_mut_rep` do nothing. Since the tests aren't
built for WebAssembly, we have to replace `console::log` with
`console_log!` in all of the functions they use. We'll eventually want
to do this replacement everywhere.
