This PR fixes issues in TableDatabase. TableDatabase is a wrapper of underlying ethdb.Database with an additional prefix. The prefix is applied to all entries it maintains. However when we try to retrieve entries from it we don't handle the key properly. In theory the prefix should be truncated and only user key is returned. But we don't do it in some cases, e.g. the iterator and batch replayer created from it. So this PR is the fix to these issues.
