Change chat log message to indicate actor name instead of assigned player's actor.

A player is owner of 2 actors: their character (Ruben) and an animal companion (Chester). Whenever the hit points of Chester is adjusted, the chat message indicates "Ruben loses 12 hit points" instead of "Chester loses 12 hit points". Can this be fixed to show the actual actor name instead of the actor that the player assigned to themselves in player configuration?
