Scheduled deletion of users account does not work

[christad92]

When user requests to delete their account, we have a grace period which is automatically set as the scheduled deletion date for the account. On the date, the account and every data associated with the account should be wiped off the database.

This does not work at the moment - see table below for a list of deleted accounts, the records are still on the database even after the deletion period has passed.

The expected behaviour here is that the account is deleted as well as owned projects and credentials.
