Nativeize assets fails with Set/Map variable for character

Nativeize assets fail with the new variable types introduced in 4.15. This issues also occurred when tested using the third person character template

Build fails with:

FirstPersonCharacter__pf205484891.h(43) : Error: Unrecognized type 'AFirstPersonCharacter_C' - type must be a UCLASS, USTRUCT or UENUM

Rudy T - Further testing shows that this can be reproduces with any actor reference that has been changed to a TSet or a TMap

1. Create a new project with the first person template no starter content needed
2. Open Project Settings > Packaging > Blueprints > Blueprint Nativization method set to Inclusive
3. Open the First Person Character Blueprint > go to event graph
4. create a new variable of type First Person Character and make it a reference
5. Go to the details panel for the created variable and next to variable type make sure that its type is set to set (Screenshot_01)
6. Compile and save the blueprint
7. Package the build for windows 64 bit
   Result: Build fails on the variable created
   Expected Result: The build should package without an issue
