DeePKS should update pdm before outputting labels #5856
Description
Describe the bug
When outputting DeePKS labels, pdm isn't updated using dm after diagonalization. This results in gevdm and precalc of force/stress/bandgap/hamiltonian being calculated using the older dm.
However, Hamiltonian matrix and other things are calculated using the new dm.
This may cause inconsistency.
Expected behavior
DeePKS should update pdm before outputting labels
