Use latest from sdk create/update for rm.onError() (aws-controllers-k8s#344)

Issue #, if available: aws-controllers-k8s/community#1336

Description of changes:
* After the sdkCreate/sdkUpdate call, the resource manager was still using the latest from ReadOne call when invoking `rm.onError` method
* Instead it should use the resource returned from sdkCreate and sdkUpdate call
