auth_token middleware have twice cache for a valided token

when a user_token == UUID_TOKEN_LENGTH(32) ,it means the code execu data = self.verify_uuid_token(user_token, retry)

            if (len(user_token) > cms.UUID_TOKEN_LENGTH):
                verified = self.verify_signed_token(user_token)
                data = json.loads(verified)
            else:
                data = self.verify_uuid_token(user_token, retry)
            self._cache_put(user_token, data)

in verify_uuid_token function ,if the the user_token is valided(200),it will cache the user_token and data,

if response.status == 200:
            self._cache_put(user_token, data)
            return data

so ,when function return, the main code also cache again.

i think ,it only need to cache once ,when function return.
