Delta restore doesnt work

[Fernando Rola Ferreira Filho]

In barman 3.14.x, when I ran a `barman restore` on a non-empty `pgdata` , the restore performed an incremental restore. In barman 3.16.x, it says the `pgdata` is not empty, which is fine. But when I use the `--delta-restore` flag, it doesn't say the `pgdata` is not empty, but it doesn't perform an incremental restore. It deletes the `pgdata` file, creates it again, and does a full restore. Has anyone else experienced this?

Commands:

`barman -d restore --get-wal --remote-ssh-command 'ssh post...@x.y.w.z' main latest`

`barman -d restore --delta-restore --get-wal --remote-ssh-command 'ssh post...@x.y.w.z' main latest`

Hey Fernando,

Can you open a Github issue in the Barman repo with these details? I think this is a bug and other people might eventually face this.
