Sparse Class Data does not work 5.4

I have an actor which was placed in the scene in 5.4 preview which reference its Sparse Class Data in its construction script. Now in 5.4 official release, the sparse class data is nullptr which result in a crash.

Big sadge, my project crashes on launch

While you’re at it, fix this as well. Sparse class data seemed nice, but am leaning on never touching them again…
