Alerts queued for daily dispatch are never sent

[Morten Brekkevold]

A user reports that his profile contains a subscription to queue all alerts and dispatch them at the daily predefined time of 07:30. This alert profile has been active for some time, yet no queued alerts have been received.

A quick look at the database shows that the accountalertqueue table contains 1575 entries related to this user, and the number is growing.

The complete profile of the user is as follows:

08:00:00 - 16:00:00, weekdays

    * Watch G10: All box up/down alerts, send to <email address hidden>, immediately.
    * Watch G01: All alerts, send to <email address hidden>, daily at predefined time.

16:00:00 - 08:00:00, weekdays

    * No subscriptions watched in this time period.

The diff:
- return (sent_daily, sent_weekly)
+ return (sent_daily, sent_weekly, num_sent_alerts, num_failed_sends)
from http://metanav.uninett.no/hg/default/rev/d6bb97c89d85 is also relevant, but unfortunately ended up in the wrong commit.
