ui,nodes: improved adding nodes to the db

When a node connected to the gui for the first time, we were not
updating the db accordingly. We were doing it when populating the
stats or adding events.

Unfortunately, not all fields are available when a node subscribes to
the GUI, they're sent when the node posts new events. Because of this,
some fields may appear blank until the node send new events.

It'll be fixed in future releases.
