Fixing handleDocument.fetchAll to fetch documents things.

The problem:
The Social.get works synchronously and returns null if it's still loading and cause the widget code to rerender only once, but in the case of fetchAll, we are fetching the project documents array first, then fetching each document alone, that means multiple retriggers are needed to not get null, but the init function is only getting 2 retriggers.

The solution:
The not so good solution I come out with, is to keep rerendering the widget code every 1s until fetchAll stops returning null. I don't like this solution, and I think the better way is to use Social.asyncGet and save the data in state or cache.
