func (p *triePrefetcher) trieID(owner common.Hash, root common.Hash) string {
return string(append(owner.Bytes(), root.Bytes()...))
}
so the new key will be changed from the root to string(append(owner.Bytes(), root.Bytes()...))

This PR is to:
prefetcher. Currently, each trie is represented by its root hash. There will be a case when two accounts have exactly the same storage information, and thus the same root hash of storage trie. Adding the owner information helps distinguishing them correctly, and each account has its own storage trie now.(t *Trie) Commit(), if the trie is clean (maybe committed earlier) and nothing-dirty-to-commit now, there might still be some resolved nodes (maybe retrieved earlier), but the tracer isReset(), so it will lose the information regarding those nodes. This PR set the root to its hash to ensure that all nodes are released afterCommit().
