Subject: [PATCH] Fix client rendering skulls from same user
See: https://github.com/PaperMC/Paper/issues/1304
Changes the UUID sent to client to be based on either
the texture payload, or random.
This allows the client to render multiple skull textures from the same user,
for when different skins were used when skull was made.
