Checking localStorage first before fetching from server

[chiplay]

I might be missing something, but having trouble getting collections to load from localstorage. When I implement dualstorage and run fetch on a collection - the data is fetched from the remote server and saved into localstorage - as expected. But when I refresh the page, the API request is made again - instead of the data getting retrieved from localstorage. When I turn off wifi and refresh, the data is retrieved from localstorage correctly, even though it still makes a failed API request.

Is this the correct behavior for dualstorage?

We've toyed around with this idea before, but at least the way it was implemented, there was a pretty decent performance penalty - see #16.

What I did to achieve the behavior you're looking for was create a local method in my collection that returns true during my initial fetch, so that I can get local data immediately if it is available, and then fetch again to pull from the remote as usual.

I'm open to ideas about how to better approach this.
