Unit tests in nested classes can't be run or debugged

[veggerby]

It is not possible to use a unit test structure like the one suggested by Phil Haack, combined with VS Code 'run test' or 'debug 'test'.

Steps to reproduce

1. Add a project.json with the following contents:

{
  "version": "1.0.0-*",
  "dependencies": {
    "xunit": "2.1.0",
    "dotnet-test-xunit": "2.2.0-preview2-build1029",
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.0"
    }
  },
  "testRunner": "xunit",
  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dnxcore50",
        "portable-net45+win8"
      ]
    }
  }
}

1. Add Test.cs with the following contents:

using Xunit;

namespace TestTest
{
    public class Test
    {
        [Fact]
        public void Should_hit_breakpoint_and_it_does()
        {
            System.Console.WriteLine("Should hit, and it does");
        }

        public class NestedTest
        {
            [Fact]
            public void Should_hit_breakpoint_but_does_not()
            {
                System.Console.WriteLine("Should hit, but does not");
            }
        }
    }
}

1. Run dotnet restore
2. Set breakpoint to System.Console.WriteLine in Test.cs
3. Run "debug test" on both

Expected behavior

Debug test
Both breakpoints are hit

Run test

Running test TestTest.Test.Should_hit_breakpoint_and_it_does...
Test passed

Running test TestTest.Test.NestedTest.Should_hit_breakpoint_but_does_not...
Test passed

Actual behavior

Debug test
Only Should_hit_breakpoint_and_it_does break point is hit, while 'Should_hit_breakpoint_but_does_not' is not

Run test

Running test TestTest.Test.Should_hit_breakpoint_and_it_does...
Test passed

Running test TestTest.Test.NestedTest.Should_hit_breakpoint_but_does_not...
