fix(hub): the sidebar's Node section follows the node link

Reported on a real install: after the first click on Create group, the Node
section (Node, Create group) disappeared from the sidebar until a reload,
although the group was created and the node ran.

hasNodeKey was read once per session change and never again, so a node the
wizard linked stayed out of the sidebar; and that read swallowed its errors,
so a session blip (a refused renewal, then the desktop app's silent device
sign-in) followed by one failed request hid the section for good. The wizard
now tells the app when it has linked or started a node, the app asks again
then and after a group is created, and a failed read is retried -- never
applied to a session that has changed meanwhile.

The wizard also starts the node on its own for a node in waiting_for_hub.
