ReSharper8 beta test runner bug.

Two branches here, one called 'passing' one called 'failing' to show both states. This is a replication of an issue in a real codebase, so some of the conditions may be irrelevant

Solution has a few nested solution folders.

• OtherCode [.NET45 project]
• OtherCode.Test.Unit [.NET45 test project]
• AnEx86Project [x86 .NET4 project]
• AnEx86Project.Test.Unit [x86 .NET4 test project]
• ReSharper8TestRunnerBugRepro [.NET35 project]
• ReSharper8TestRunnerBugRepro.Test.Unit [.NET40 test project]

When "Run all tests" is clicked

• OtherCode.Test.Unit = PASS
• AnEx86Project.Test.Unit = PASS
• ReSharper8TestRunnerBugRepro.Test.Unit = FAIL

The failure is always reading configuration files in our real solution, and the test in this repo replicates that.

When "ReSharper8TestRunnerBugRepro.Test.Unit" selected in test runner and clicked "Run Unit Tests"

• ReSharper8TestRunnerBugRepro.Test.Unit = PASS

When I remove OtherCode and OtherCode.Test.Unit

• AnEx86Project.Test.Unit = PASS
• ReSharper8TestRunnerBugRepro.Test.Unit = PASS
