Make sure that extinct entries aren't shown in the endosymbiosis candidates (verify bug report)

So that the player isn't tempted to try to endosymbiosise something that is extinct. Related to: #5749

I think the pruning should happen at the level of the engulfed species count as that list might otherwise never be cleared of extinct species that never exist again.

So a simple clean up once auto-evo is done in the editor for the player engulfed species list to remove entries of extinct species could be added.

Any way to reproduce this quickly? And what's this?

[hhyyrylainen]

Just engulf some stuff and play a couple of generations? At least some of the species should go extinct so this should be actually an easy condition to trigger.

And what's this?

Oh, that should already be the case then...

I'll retag this as verifying the code works, and if it does work then this issue can be closed.

The linked part is only called when making the list, right?

Wild guess: list is not re-made after said species go extinct?
