Contains a workaround for https://issuetracker.google.com/issues/177245496. Due to the way which paging loads data, it will always result in an initial empty state, and then the loaded items. That conflicts with the way which rememberLazyListState() and friends store their state, as they rely on the items being present at the time of (Android) state restoration. To workaround this, we use a different LazyListState while the lazy paging items are empty, and then switcheroo to the standard state once we know we have the items available.
