* Prevents possessed blade spirits and similar entities from being created in a destroyed parent item (#76978)
## About The Pull Request
Activating any item with a `spirit_holder` component to poll for a new
spirit, then destroying the item before the poll process is completed
would create the spirit in nullspace, which would then dump them to the
error room. These spirits are in GODMODE by default, but are usually
contained within an item. See the issue?
This PR makes the spirit creation process check for whether the parent
item was deleted or not before actually creating the spirit. If the
summoning item was destroyed, the would-be spirit will get a message
about it so they can brag about it in deadchat
## Why It's Good For The Game

Loosely adapted from /vg/. This is an entity component system for adding behaviours to datums when inheritance doesn't quite cut it. By using signals and events instead of direct inheritance, you can inject behaviours without hacky overloads. It requires a different method of thinking, but is not hard to use correctly. If a behaviour can have application across more than one thing. Make it generic, make it a component. Atom/mob/obj event? Give it a signal, and forward it's arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
