test: update chunk file name to reflect new name

It seems that the chunk deterministic name has changed after
recent node module /lock file changes. It's unclear what specifically is
involved in Webpack's chunk name generation, but the output and all
other tests still look good; which makes this is a rather safe update to
the new chunk name. Consulting with CLI team members explained that this
can happen quite often.
