lib: ignore VS instances that cause COMExceptions

I have quite a few instances of VS installed and it looks like Find-VisualStudio.cs enumerates all of them, even when find-visualstudio.js already knows which one it wants (from the environment variable in the developer command prompt). One of them (from 15.7.2, if that's interesting) causes a COMException on the ISetupInstance2.GetPackages call. Ignoring such packages seems harmless and unblocks the rest of the run.
