fix(test): assert normalized callback dest in extractPackage test

extractPackage now hands the callback a forward-slash-normalized dest, so the
'should call callback with destination path' test must compare against
normalizePath(dest) — the raw path.join() dest is backslash-separated on Windows
and the string-equality assertion failed there.
