Actor reference in actor component is cleared after the containing actor is compiled

A variable with an actor reference that is owned by an actor component will lose it's reference if the actor that it is applied to is compiled. 

1. Open the attached project
2. Open Test level 
3. Select the actor in the level 
4. Scroll through the component list of the actor in the detail panel
5. Select "TestActorComponent"
6. The setting for the variable "Actor" will be set to "Broken snowman" by default
7. Open "TestPawn" in the content browser
8. Add a print string to the event graph 
9. Compile 
10. Select the actor in the level again
11. Scroll through the component list of the actor in the detail panel
12. Select "TestActorComponent"

Result: The reference for the actor variable will be lost (will be set to None)

Expected: The reference that was provided would remain the same after compilation
