BaseOAuth method - `refreshAccessToken` sends request when no refresh token exists

[kalmerkaurson]

I receive 400 error when I use method getAccessToken() of class \yii\authclient\BaseOAuth, and no refresh_token is present for the token.

What steps will reproduce the problem?

1. Set $autoRefreshAccessToken to true for \yii\authclient\clients\Oauth2Client
2. Authenticate client with a token that does not contain refresh_token
/** * @var \yii\authclient\clients\Oauth2Client $client */ $client->authenticateClient();
3. Wait for token to expire
4. Use getAccessToken method to get access token
   /** * @var \yii\authclient\clients\Oauth2Client $client */ $client->getAccessToken();
5. I receive 400 error from refreshAccessToken method, because refresh_token was not present in the token

What's expected?

Request is not sent out when refresh_tokenis not present and the old token is returned instead.

What do you get instead?

I receive 400 Refresh Token cannot be blank.
