Add JavaScriptEngineSwitcher references to avoid issues with older MSBuild

MSBuild 12.0 and below have started throwing errors like "The type 'JavaScriptEngineSwitcher.Core.IJsEngine' is defined in an assembly that is not referenced. You must add a reference to assembly 'JavaScriptEngineSwitcher.Core, Version=1.2.4.0, Culture=neutral, PublicKeyToken=c608b2a8cc9e4472'" with the build. Referencing JavaScriptEngineSwitcher in more assemblies was enough to make it happy. Strangely, MSBuild 14.0 was fine before this change.
