Fix refreshing of the credentials in case the refresh token is expired

[azerty9971]

If the call to refresh the access token fails because the token is expired then the result of the new connect (which is a new refresh token and a new access token) should be stored in the TuyaTokenInfo that is created in the __refresh_access_token_if_need (line 168).

Without this code, the returned payload is the error one (code 1010) and is thus stored in the TuyaTokenInfo instead of the newly retrieved credentials.
