backup: Add PRAGMA foreign_keys=on when restoring so cascades work
...
We heavily rely on foreign key constraints to keep the DB consistent and drop
dependent objects such as UTXO set entries when we roll back a block. We also
need to enable the foreign key constraints when restoring otherwise these
dependents are not removed and we run into constraint violations.

backup: Temporarily use a wrapper of the node_factory
...
The node_factory from pyln-client clears the node directory when provisioning
a new node, which interferes with the backup-cli creation of the initial
snapshot. This just disables the cleaning until we can release the next
pyln-client version
