Expiry/inactivity warnings try to email invalid addresses

[Richard Mansfield]

The cron job to send account/institution expiry and inactivity warnings doesn't check for deleted users or invalid email addresses. If there's even one deleted user in the list, it will cause cron to die, so other users are never warned.

    Don't send expiry/inactivity warnings to deleted users (bug #903485)

    Users are emailed on cron to warn them about impending account expiry,
    inactivity, or institution membership expiry, but deleted users are
    included in the list, resulting in attempts to send email to invalid
    addresses.

    Notify internally when trying to warn users with invalid email (bug #903485)

    When expiry/inactivity warnings are sent, invalid email addresses
    throw exceptions, so the cron script will fail. It is better to catch
    the email exception and insert an internal notification instead. For
    account expiry/inactivity, it is unlikely that the user will ever read
    the warning, but it may be useful for institution membership expiry.
