This should be unreachable since we're looking at a parent node in the tree

We can avoid the cloning by doing the contains check inside of the match
match &self.nodes[parent] {
Node {
content: Content::Container(container),
..
} => container.children.contains(child_id),
_ => unreachable!(),
}

This would fix #1083.
Right now there's this error happening: #2773 (comment), when you do an appropriate amount of vertical splits.
This is the line that causes the crash:
helix/helix-view/src/tree.rs
Line 408 in fd585c1
I think recalculate() here doesn't take into consideration that inner gaps decrease area width, so I changed that.
I also added a function in typed.rs that checks if a child view of the focused view has a width of 1. If it does, then we can't make any more vertical splits.
