Fixes

1. Minor fix to not write the image object data to dynamo on updates. For articles and videos the imageName string defines the card name/set and the hydration uses that to load the image object from the dictionary
2. Fix loading more podcast and videos in the Content creator dashboard. Those pages were trying to load more articles which leads to a dynamo error about the predicate not matching the last key cursor
