MolStandardize: cleanup() function not correctly reassigning stereochemistry

In [9]: nm.GetAtomWithIdx(1).GetChiralTag()
Out[9]: rdkit.Chem.rdchem.ChiralType.CHI_TETRAHEDRAL_CCW

Given that the charge has been moved to the carboxylic acid group, the chiral tag should be UNSPECIFIED:

In [10]: Chem.AssignStereochemistry(nm, force=True, cleanIt=True)

In [11]: nm.GetAtomWithIdx(1).GetChiralTag()
Out[11]: rdkit.Chem.rdchem.ChiralType.CHI_UNSPECIFIED

Configuration (please complete the following information):

• RDKit version: 2022.03 and master
• OS: all
