StateDB proof/verify is not working

[shuse2]

Expected behavior

StateDB.verify and StateDB.proof should be the same interface as SparseMerkleTree.verify and SparseMerkleTree.proof.

Unit test on JS should be added to ensure the interface is correct. Note that StateDB key is by default.

Actual behavior

The internal smt.verify and smt.proof is used for both in memory and state db, but bridge between js and rust is not working.

Steps to reproduce

describe('proof', () => {
            it('should generate proof and verify the result', async () => {
                const queries = [getRandomBytes(38), getRandomBytes(38)];
                const proof = await db.proof(root, queries);

                const result = await db.verify(root, queries, proof);

                expect(result).toEqual(false);
            });
        });

above unit test should pass in the state_db.spec.js
