Recreate nested nav to work with AnimatedPane

[alexvanyo]

Adds AnimatedPane to ListDetailPaneScaffold for interests by introducing a workaround for the nested navigation host setup.

Previously, adding AnimatedPane would crash when just the list was showing, since we'd try to call navigate on the nested nav controller before the graph for the nested nav controller was setup.

The workaround in this PR is to only call navigate on the nested nav controller in the situation where both the list and detail are showing.

If just the list is showing, then instead of calling navigate on the nested nav controller, we completely tear-down and recreate the nested nav controller and the nested NavHost via a key on a unique id. Then, the start destination of the nested nav host becomes where we were trying to navigate to.

Since we were popping the nested nav controller anyway, we don't mind that we completely wipe the state of the nested nav host in this situation.
