In the scope of CSHARP-2914, we added cake packaging tests only for sdk csproj files. To cover all cases, it would be good to support tests for non-sdk tests also, But it's a bit tricky since non-sdk projects cannot be created via CLI (only modified), so we need to think about how we can reach this goal.

Also, in the previous tickets, consuming the nuget in non-sdk project via powershell or Package Manager Console didn't work (due some issue between nuget v2 and v3), not sure whether we even can create these tests. It should be investigated further
