ThrowingTraceListener specified in tests\Common\Test\App.config doesn't exist

[tmat]

The configuration specifies Microsoft.VisualStudio.ProjectSystem.Managed.TestServices assembly name, but the project containing the type is a shared project and there is no such assembly.

<add name="ThrowingTraceListener" type="Microsoft.VisualStudio.Diagnostics.ThrowingTraceListener, Microsoft.VisualStudio.ProjectSystem.Managed.TestServices" />

The share project needs to be converted to a regular dll.

Tracking TODO in code.
