This change ensures the database and extension is validated whenever these objects aren't created, instead of only doing validation when `bootstrap=>false` is passed when adding a data node. This fixes a corner case where a data node could be added and removed several times, even though the data node's database was already marked as having been part of a multi-node setup. A new test checks that a data node cannot be re-added after deleting it on the access node, irrespective of whether one bootstraps the data node or not when it is added.
