test(core): parse optimization status regardless of forced color

With FORCE_COLOR set, as in an interactive terminal, console.log colors
the numbers it prints, so the `done <before> <after>` regex never matched
and both optimization tests failed. Print a single interpolated string,
which is never colored.
