Despite all of our efforts, gmail insists on marking our verification emails to
new users as spam. We have already changed our mail delivery providers;
non-gmail users don't face this problem; and even for gmail, (a) existing Ente
users also get these mails correctly with SPF/DKIM/DMARC PASS, and (b)
non-verification emails get delivered (in the anecdotal reports we've received).
As an attempt at some voodoo, try changing the subject and content of the mail,
to try and rule out some faulty gmail classifier that uses the email body.
## Description
For accounts that were recovered post deletion (within x days), we were
not removing the entry from data_cleanup cron.
The data_clean up cron anyways verify that the account is indeed deleted
before proceeding with deletion, so it was not causing any harm, but the
cron was logging error.
## Tests
- [x] Verify that data clean up entry is removed if the account is
recovered
- [x] Verify that for existing data_cleanup entry for already recovered
account, the entry is deleted from cron.
