on_death overrides (not overloads)

Event 110044 in the maintenance_events.txt was never running because
other files were overwriting the on_death pulse with limited lists.
Could be unintended consequences to re-enabling 110044 but it fixes the
bug where Vassals would leave your Kingdom if they died during some
civil wars.
