get_block out put dose not match between cli and db_api

currently the cli wallet response and the db_api response do not match when calling get_block()

optional<signed_block> get_block(uint32_t block_num) const; // from db api

vs

optional<signed_block_with_info> wallet_api::get_block(uint32_t num) // from cli wallet

both should respond with <signed_block_with_info>
