A wrong DMC calculation with multideterminants wavefunctions

[huangxxxxxxxx]

Describe the bug
We generate a multideterminant wavefunction by GAMESS for N2 molucular, the optimization progress is successful, However, when we do DMC calculation, the energy of DMC is drop a few hartree. it is worth noting that the N2 molecular is at twice the equilibrium bond length.

To Reproduce
Steps to reproduce the behavior:

1. release version or git commit hash being built
2. cmake command
3. full program/test invocation command
4. additional steps

Expected behavior
A clear and concise description of what you expected to happen.

System:

• system name [e.g. fusiont5, summit]
• modules loaded [e.g. output of module list]
• other systems where this is reproducible [e.g. "my laptop", "none"]
