\#wizkill vs dmonsfree

When testing the high priest livelog/#chronicle feedback I used #wizkill
on the Sanctum level to kill Moloch's high priestess and immediately
level teleported to the Astral level to target the other high priests.
I got impossible "dmonsfree: 0 removed doesn't match 1 pending" there.
