Description

Actor->Actor hard references trigger a warning when trying to delete the referenced actor in the level editor(UUnrealEdEngine::edactDeleteSelected). Actor->Component->Actor references do not trigger a warning. Looks like the ActorReferenceMap does not consider references serialized in components. 

Steps to Reproduce

From the reporting UDN:

Given an Actor A which has an Actor Component with an Object Reference (Hard Reference) Property, and given this Property being set with a Reference to Actor B in a Level.

When deleting Actor B, no Message Box appears, warning of the Reference that will be broken, and the Property of the Actor A Actor Component is reset to None.

Expected Result: As with an Object Reference (Hard Reference) directly on an Actor, the user should see a Message Box appear when trying to delete the Referenced Actor (see below for an example).
