* This CL fixes the referenced bug, but it does NOT explain how
mAccount; best guess is that the process was killed and then
restarted when the result from DPM was available.
* Assuming this is the case, we remove the background task loading
mAccount, avoiding a possible race.
* Also, it's not clear why clearNotifications didn't use the
account id argument; what if there's more than one account that
uses security? Filing a bug about this.
