[23.2] Fix social_core methods

[jdavcs]

Should fix #17508, for real this time.

These were cleverly refactored in #16724, and that broke things because the methods are used by social_core. I've restored the original behavior and added comments to each method to prevent future 'optimizations". I've rearranged the methods to mirror the parent class in social_core/storage.py (in .venv).

Also see #17516.
