tests: add a "missing" tests for manifest content in test-racy-mutations.t

Trying to figure out why the divergence in behavior on Windows.  The first test
shows everything is the same on all platforms; the second shows that the other
#testcase also diverges.  The difference might be that `00manifest.i` doesn't
get updated (and copied over) after `pre-race` is created, but I've no idea why
that would be either.
