Cleanup not running in 4.0

[megatwig]

Summary

cleanup_old_data() is no longer called as part of the backup routine.

Automatic cleanup that worked fine under v3 stopped working since v4. I realised when a disk ran out of storage from being filled up with database backups that had stopped being cleaned up. I tried changing my old environment variable from DB_CLEANUP_TIME to DEFAULT_CLEANUP_TIME, and also DB01_CLEANUP_TIME to no effect. No logs in the console about cleanup running.

The cleanup_old_data function no longer appears to be referenced anywhere in this repo, so I guess the step got accidentally dropped from the backup script when it was migrated.

Wow - this is embarrassing that I omitted this. Fixed in 4.0.15

Updating now. I just noticed the same lack of cleanup as my disk is now at 90%. Thanks!
