[keycloak-dev] IDP Refresh token lost on first refresh during internal to external token exchange

When performing an internal to external token exchange, if the requested IDP access token is expired, Keycloak performs a token refresh using the originally obtained access token. After the operation is complete, the original token response is discarded and the new one is saved; unless the new one includes a refresh token, the refresh token is then lost and subsequent token exchanges requiring an IDP token refresh will fail. This happens regularly with Google as an IDP, since the token refresh response does not include a refresh token, which is only provided in the original authorization code exchange. I have a patch to OidcIdentityProvider which ensures that the original refresh token is saved if a new one has not been provided during the token refresh operation. Should I proceed and provide a PR?
