Use the AttackTarget state change instead of agent naming

[Sejsel]

Currently, we rely on attack target names instead of properly attributing them by using attack target state changes describing their relationships. If logs do not contain proper names, finding the parent of an attack target fails.

Found by comparing with EI.
