Issue Description

When you splash mitochilde on dismembered limb there is a runtime error which prevent mitocholide from rejuvenate a limb and block half of its functional due there is no check for owner of limb is not null

What did you expect to happen?

The limb should call rejuvenate proc without errors

What happened instead?

It's simply fails due execution

Why is this bad/What are the consequences?

It's block an ability of mitocholide to remove bone breakes, internal blidings and critical burns from handling

Steps to reproduce the issue.

Simply spawn limb, splash mitocholide on it, check run time error in:
code/modules/surgery/organs/organ_external.dm
384 - /obj/item/organ/external/rejuvenate()
390 - if(HAS_TRAIT(owner, TRAIT_I_WANT_BRAINS))
there will be no owner, so there will be error

When did the problem start happening?

When zombie mode was implemented

Extra information

To fix it simply add a check.
Maybe something like this:
status = 0
if(is_robotic()) //Robotic organs stay robotic.
status = ORGAN_ROBOT
else if (owner)
if(HAS_TRAIT(owner, TRAIT_I_WANT_BRAINS))
status = ORGAN_DEAD

and something like this futher:
if(!HAS_TRAIT(owner, TRAIT_I_WANT_BRAINS)) // zombies's wounds don't close. Because thats cool.
open = ORGAN_CLOSED
