plugin pubsub cache: resync in `synchronise` when node's `sync_state` is not set: synchronisation used to be skipped when the node was existing and `resync` was not set, however the case happens when a node is subscribed but not synchronised, thus this patch update the behaviour to be sure to have the node synchronised. rel 369
