Subject: [PATCH] Upgrade/Install: Check that WordPress is installed before
 scheduling cleanup of the `temp-backup` directory.

Trying to schedule cron jobs before WordPress is installed results in DB errors, which is suboptimal.

This addresses a  `Table 'wp_options' doesn't exist` error when running the installation with `WP_DEBUG` enabled.

Follow-up to [51815], [51898], [51899], [51902], [52192].

Props dlh, pbiron.
See #51857.
