Aws-sdk-ios: awscognitoauthclienterror check always fails

AWSCognitoAuthClientErrorType and Error are not the same type, so it never works as expected

Yes, now when the user's token is completely invalid, requesting the getTokens method will trigger an errorExpiredRefreshToken(-7000) error. At that time, as mentioned above, this conversion method will always fail, resulting in our listeners never having the opportunity to get signedOutUserPoolsTokenInvalid notification.

The right code should be like below:

if let error = error, let cognitoError = AWSCognitoAuthClientErrorType(rawValue: (error as NSError).code) {
    if cognitoError == AWSCognitoAuthClientErrorType.errorExpiredRefreshToken {
        ...
    } else {
        ...
    }
}
