Navigation restarts when host Fragment gets restored

[Miha-x64]

If we're inside a Fragment, ComposeView gets destroyed when we're put to back stack and re-created when popped back. Under these circumstances remember() forgets everything but rememberSaveable() still works.

PreCompose/precompose/src/commonMain/kotlin/moe/tlaster/precompose/navigation/NavHost.kt

Lines 95 to 97 in 32bf75f

	LaunchedEffect(builder, initialRoute) {
	navigator.setRouteGraph(
	RouteBuilder(initialRoute).apply(builder).build(),

LaunchedEffect() relies on remember(). Thus, navigation gets restarted, and even rememberSaveable() are useless inside destinations.

It might be better to find a new way to initialize the route graph, currently PreCompose still want to reset the route graph when builder or initial Route changed.
