refactor(router-core): router uses .some() over .find() for boolean results (#4829)

This change is a no-op, even in terms of performance. But it's more of
an "anti-slippery-slope" measure, so we don't end up with array copying
methods like `.map` or `.filter` being used instead of simpler methods
like `.find` or `.some`
