Inserted tongues and HUD implants no longer exist outside the body. (#71737)

## About The Pull Request

Fixes an odd bug reported in #71699. Due to a minor error, tongues and
HUD implants, when inserted with organ manipulation, would _also_ drop
on the floor. This was not duplication, as originally suggested, but was
in fact the actual organ inserted. This could lead to _extremely_ odd
behavior, where you could do things like steal someone's tongue and eat
it later to remotely remove it from them. This no longer happens.
## Why It's Good For The Game

Organs should not exist outside of the body once they've been inserted.
Mind you, it could be _interesting_ if there was an intentional way to
do something like this (holding someone's organs hostage or something of
the sort), but as a bug it's both obtrusive and confusing.
