fix(home): fix see all sometimes opening empty screen

[marcin-kozinski]

In this episode of Slate IDs Don't Matter it turned out we load slates by slate id on the details screen. And if you click "See all" while Home is refreshing, you'll start the screen with an id, but when the network request comes back all the ids will change and the screen won't find a slate with this id and will show and empty screen.

In this case opening by index is more reliable. The only bad things that could happen is if we remove a slate or reorder them. Then someone could see a different slate than the one they clicked. Unless we reorder slates on each refresh, they should be able to just go back and reopen to get the correct one.
