Blueprint breakpoints on EventEndPlay do not break execution in PIE

Blueprint breakpoints on EventEndPlay do not break execution of the PIE session before the session is destroyed.

1. Create an actor Blueprint and add an EventEndPlay node to its graph and wire a print string node to it.
2. Add a breakpoint to the EventEndPlay node.
3. Add an instance of the actor to the level and PIE.
4. Quit PIE and note that while EventEndPlay was called, the PIE session is torn down without triggering the breakpoint.
