* fixes ebolas whiffing on prone targets and leaving junk behind (#83708)

## About The Pull Request

Makes energy bolas work on prone targets and not leave behind garbage
when they'd whiff.

Ever notice how you could crawl through one unlike other bolas and how,
if you got hit by one while prone, it left behind a little blue
bear-trap looking thing?

#60160 gave them the ability to be blocked and to hit flying mobs, but
it did this by making them create a subtype of bear trap on the location
on hitting a valid atom. This meant that if the target lacked a leg, was
prone, or already had a bola on, the bear trap object would be left
behind and the bola would do nothing.

This fixes that. Does not seem to have been intended behavior.

## Why It's Good For The Game

Fix good.
