NullReferenceException in BuildComponentEntry: LoggingService is null

We specify `null` for the LoggingService here:
https://github.com/Microsoft/msbuild/blob/a80ce1f1ec82586a946e0a3edcfb0fa760732133/src/Build/BackEnd/Components/BuildComponentFactoryCollection.cs#L80

and then attempt to access the _factory (which is null) for logging service here:
