What's new in this PR?

Issues

When we navigate around screens sometimes the conversations are not visible until we scroll the list manually.
It looks like there are three different scenarios:
-the full list disappears for a moment when navigating back
-the list blinks quickly and then again blinks quickly when scrolling
-the list doesn't blink but then it disappears when scrolling

Causes (Optional)

Each scrollable screen from "home" graph in theory has its own LazyListState, but each view for its own purposes gets it through the currentLazyListState. Now, when app executes navigation and changes the currentNavigationItem, if the screen that's being closed still needs to recompose during the transition animation or quickly before that, then it again gets the LazyListState for itself using currentLazyListState but now it returns the LazyListState for the new screen that's being navigated to, because currentNavigationItem is already changed, so it recomposes with wrong LazyListState.

Solutions

Make each screen in the "home" graph to always and only use its dedicated LazyListState.

Thanks to that, it's finally possible to make HomeStateHolder not being remembered with key currentNavigationItem thus recreated each time the app navigates, but instead there is only one instance of it remembered and the same one is used in each screen from "home" graph.

Testing

How to Test

• Open navigation drawer
