Delete Praefect DB upon running restore rake task
<!-- This template is a great use for issues that are feature::additions or technical tasks for larger issues.-->
### Proposal
Currently the backup task only clears production DB when restoring. The Praefect database gets over written only for the repositories that get restore. See [slack discussion](https://gitlab.slack.com/archives/C3ER3TQBT/p1665509772839789)
When there are more repositories on the DB than being restore, this can cause issues when creating new projects. See [zd-294970](https://gitlab.zendesk.com/agent/tickets/294970)
The proposal is to wipe Praefect DB and storage prior to restoring repositories.
