factor::miller_rabin: Minor improvements#1562

Conversation
The duplicate work was introduced in 2015.
Ignoring a value of that type is a bug: they are only produced by `miller_rabbin::test`, which is a pure, but expensive, function. As such, an ignored value is always either a mistake, or an easy optimisation opportunity (just remove the useless call to `test`).

Will conflict with #1554, but the merge should be pretty trivial.
