Drop codec spam fix (Fixes #5936)

Browse Source 
having spoken to mojang about this the general issue is data which shouldn't
have been saved in the first place, so if we lose this data it's not really
an issue, bar being annoying spammy. if the spam gets on your nerves, shamefully,
all you can really do is forceUpgrade to get the conversions of the way.

Dropping as this breaks other aspects of the server and bar being spammy
seems to have no other real negative outcomes

Subject: [PATCH] Fix Codec log spam
Mojang did NOT add dataconverters for world gen configurations
that they CHANGED. So, the codec fails to parse old data.
This fixes two instances:
- IntProvider is new and Mojang did not account for old data.
Thankfully, only ColumnPlace needed to be special cased.
- TreeConfiguration had changes. Thankfully, they were
only renames for one value and thankfully defaults could
be provided for two new values (WITHOUT changing behavior).
