Not properly detecting changes to "solution-wide" files

Had a PR in Phobos with some package upgrades to Directory.Packages.props and the build output looked as follows:

Using Incrementalist to build affected projects

Looks like the SolutionWideChangeDetector didn't get good information here.

Just had the same issue with Directory.Build.props too
