Erik Nordström c224bc7994 Always validate existing database and extension
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.
