[1.4.3510] Dig up colonists corpse, get rid of it, have a second funeral

[Kopp]

1. Circumstances:
RW1.4.3510 + Ideology. New game.

2. What happened:
After having a funeral for a dead colonist it is possible to have a second one if the dead colonist/corpse gets dig up and the corpse gets butchered/destroyed.

3. What you expected to happen:
It should only be possible to have one funeral per pawn.

4. Steps we can follow to make the bug appear on our machine:
- have at least 2 colonists, kill colonist A
- have a empty grave, assign colonist A to that grave, burry colonist A
- right click on the grave -> funeral for pawn A. Wait until funeral is over.
- open the grave, get rid of colonist As corpse (butcher, dev mode destroy)
- 1 or 2 letters arrive which say "funeral opportunity for colonist A"
- right click on the now empty grave -> funeral for colonist A.
- The funeral works like without problems, so the colonists attempted both funerals have now 2 mod de/buffs.

5. Savegame?
No savegame as it is quite simple to reproduce.

6. Log?
No log file as it is quite simple to reproduce and does not spit errors

Thanks for the bug report and the easy to follow reproduction steps. I was able to reproduce this as well. I will be getting a bug report into the devs!
