UI: Don't reselect SceneTree items if tree is clearing

In the scene tree, we currently prevent deselecting items by
automatically reselecting a new one to workaround a regression in Qt 6.2
that would let users unselect items even in SingleSelection QItemViews.
When clearing however, we explicitly want to unselect the currently
selected item, so we should avoid reselecting it in the SceneTree.
