[Bug 1482940] [NEW] A bounced probe can throw AttributeError

[Mark Sapiro]

Public bug reported:

If the site has set 'VERP_PROBES = Yes', when a user's bounce score
reaches threshold, that user's score is reset and a probe message with a
confirmation token is sent to the user. If the probe bounces, the user's
delivery is disabled by bounce.

The issue is if the probe bounces, but for some reason, the bounce is
not returned within bounce_info_stale_after days, the user's bounce_info
can be deleted before the probe bounce is returned. Then the probe
processing gets the user's bounce_info which is None and attempts to
disable the member's delivery with bounce_info = None, and
disableBouncingMember attempts to get the cookie attribute from None
resulting in

AttributeError: 'NoneType' object has no attribute 'cookie'
