test(unit): converted the remaining scaffolder unit tests to vitest

tests for the base scaffolder still need a bunch of rework, but this mostly matches what was there
with mocha, so it will unblock the esm transition. mosre rework will be possible after a few of the
breaking changes go out with the new major version

closes #1276
