Test runner doesn't work with latest dotnet tooling

[roji]

Using the latest Visual Studio RC (dotnet sdk 1.0.0-preview4-004233), dotnet-test-nunit doesn't seem to work. It seems to still be targeting an old version of Microsoft.NET.Test.Sdk (15.0.0-preview-20161024-02), there may be other issues as well.

@roji Microsoft has dropped support for the test adapter API that this adapter is using in favour of the old Visual Studio adapter API. We need to update our Visual Studio adapter to support .NET Core which means adding .NET Core support to our engine. This means that this project will not work with the newer tooling or with VS2017.

We are playing catch-up, sorry. In the meantime, the workaround is to create an NUnitLite self-executing test assembly and run from the command line.

@rprouse no worries, I'm painfully aware how frustrating it is at the moment to be on Microsoft prerelease software... I'm already using an NUnitLite executable project as my workaround so this is definitely not urgent.
