[MIRROR] immortal heart attack fix (#2069)

* immortal heart attack fix (#82738)

## About The Pull Request

cybernetic hearts no longer permanently break when you die, as they
would try to restart after you get revived but then the proc to stop the
heart attack would get early returned because the heart is immune to
heart attacks

## Why It's Good For The Game

having to explode to revive because of surplus heart seems like a bug

## Changelog
:cl:
fix: being revived with a cyber-heart now properly restarts the cyber
heart
