Aikar e32b8cfddb Improve old UUID support, clean up old legacy keys.
If we set a UUID to new format, need to make sure old format doesn't
exist anymore. Additionally, ensure if new format exists, we prefer it over old.

Subject: [PATCH] Support old UUID format for NBT
We have stored UUID in plenty of places that did not get DFU'd
So just look for old format and load it if it exists.
