Move src\Test\Diagnostics\Diagnostics.csproj to be under Roslyn/VisualStudio in solution
Move src\Test\Diagnostics\Diagnostics.csproj to be under Roslyn/VisualStudio in solution

Diagnostics.csproj was under Roslyn/Diagnostics in solution, but everything there is removed and the only project referencing Diagnostics.csproj now is src/VisualStudio/VisualStudioDiagnosticsToolWindow/VisualStudioDiagnosticsWindow.csproj, so move Diagnostics.csproj under Roslyn/VisualStudio and remove Roslyn/Diagnostics from solution.
