Issue when closing node together with hide_root_node

[sQVe]

👋🏼,

I've been trying the hide_root_node setting, since it gives a cleaner look but noting that it doesn't play nicely when triggering close_node. It basically leaves you in a state that is completely empty and triggering open results in an error. The only way, that I've found, to repair the state is to press R.

Reproduce:

• Enable hide_root_node.
• Open Neotree.
• Press C.
• You're now in an empty state.
• Press CR: it should give you an error.
• Press R to reset and repair the state.

@sQVe Does making C in the top level collapse nothing suit your needs?
