Splitting slimes and magma cubes do not copy NoAI value

The bug

Splitting slimes and magma cubes to not copy their NoAI value to the new slimes / magma cubes.

This is a separate report and not part of MC-88967 since currently for all (or at least most) other conversions NoAI is copied. So in case MC-88967 becomes WAI this report can stay open.

How to reproduce

/summon slime ~ ~ ~ {Health:0f,NoAI:1b,Size:1}
