Update-Package -reinstall or Uninstall-Package won't work for .NET Framework projects

See original GitHub issue

To repo: Visual Studio 2017, start a new .NET Framework Library project targeting .NET 4.5 or 4.0. Install Microsoft.SourceLink.Github from Package Manager Console. Build, get error

error : Unable to locate repository containing directory 'c:\scratch\ClassLibrary4\ClassLibrary4

which is fine, we don’t have github set up for this project yet.

But then if you call Update-Package -reinstall or Uninstall-Package, it would give errors like this:

PM> update-package -reinstall

Manually removing packages from NuGet Package Manager UI, could remove the other two but Microsoft.Build.Tasks.Git refuses to go.

The only way I was able to get rid of it was by manually deleting the files. I also had to go into the .csproj file for my project and delete any references to it. I then reinstalled it from the NuGet Package Manager UI, and it seems to be working now.
