Deduplicate remaining duplicate spawners I could finddeduplicate_spawners

Utilities:
cat npc/*/_mobs.txt | grep monster | sort | uniq -c  | grep -v ' 1 '

cat maps/031-3.tmx | grep 'object id=' | cut -d' ' -f 5- | sort | uniq
-c | grep -v ' 1'

NB: 016-1 has another overlapping MauvePlant spawner that has
unconfigured delay (thus is not a direct duplicate). As changing it
would change game mechanis, it is out of scope for this commit.

NB: One of the 031-1 Bat dupe was probably added in
ff1acc14dcc3683aad70907c3748f. I could not extract a reason,
and did not look into who/what/why added the other duplicates.
