Compile failure adding C++ Vehicle or VehicleAdvanced pack to a project

Adding the C++ Vehicle feature pack to a project fails to compile with the following error:

CompilerResultsLog: Info Error: Couldn't find parent type for 'TP_VehiclePawn' named 'AWheeledVehicle' in current module or any other module parsed so far.
CompilerResultsLog:Error: Error D:/MyProjects/MyProject5/Source/MyProject5/TP_Vehicle/TP_VehiclePawn.h(11)  : Error: Class 'AWheeledVehicle' not found.

This does not affect the BP Vehicle or VehicleAdvanced feature pack.

This is a regression from 4.14.3 at CL 3251583

1. Create a blank project with no starter content
2. Click on the Add New button in the Content Browser and select Add Feature or Content Pack
3. Select the C++ Vehicle Feature pack and click Add to Project
4. Click No to editing the source code

Result: Code fails to compile
