docs(readme): a database-only restore keeps the current settings and migrates

Browse source 
Restoring only the database on newer code copied the backup's old
settings.py back and ran no migrations: a backup from v4.3.0 brought back
RemoteUserMiddleware and left the password validators and WAL out, with
seven migrations pending. The restore runs migrate, which changes nothing
on a rollback, and the text names every line that takes a file from the
backup.

### Restore and rollback
Restoring puts back the database as it was at the backup; changes made since are lost. Migrations are not reversed. This covers sqlite; restore a PostgreSQL database from your own backup before rolling back the code. Set `b` to the backup directory to restore. To restore the database without rolling back the code, leave out the `git checkout` and `build` lines.

To restore the database without rolling back the code, leave out the `build` line and every line that takes another file from `$b`: the commit, `local-migrations.tar`, `settings.py`, the nginx config and `/etc/default/webvirtcloud`.
