Detailed Description

Creates a SharedAsyncFetch object using an existing AsyncFetch and a fallback value that is used in case the fetched response is an error. Note that in case the fetched response is an error and we have a non-empty fallback value, we completely ignore the fetched response. Also, note that this class gets deleted when HandleDone is called.
