Network profiler tool doesn't handle names with underscores gracefully.

The NetworkProfiler and UI tool assume that ActorNames are in the format <ClassName>_<ActorName>, and is not robust against underscores in either the class name or the actor name.

However, given that using '_' is fairly common in naming (especially in BP) this causes problems.

Either the actor Class should be stored in a separate field or work should be done to ensure a unique delimiter between ClassName and ActorName is used.

1. Place a replicating actor in a level.
2. Ensure the actor has an underscore in its name (like BP_MyActor).
3. Start the game with any networking.
4. Do a network profile.
5. Open the profile in the profile tool.
6. Examine the Actor column.

Expected: Data for each actor will appear in a unique row, and every visible actor should correspond to an actor placed in the level.

Actual: Data for each actor will appear in a unique row, however there are rows that don't directly correspond to actors in the game.
