> Currently, StateBackendTestBase class does not register snapshots to SharedStateRegistry
in testValueState, testListState, testReducingState, testFoldingState and testMapState UTs,
which may cause RocksDBStateBackend to restore from PlaceholderStreamStateHandle during the
2nd restore procedure if one specific sst file both existed in the 1st snapshot and the 2nd
snapshot handle.
