Bug 823285 fixes the problem where Fennec is killed while private downloads are in progress, but it doesn't fix the case where the last private context is closed while Fennec is running. For that, we should iterate through the list of active downloads and clear the notifications on last-pb-context-exited. From https://bugzilla.mozilla.org/show_bug.cgi?id=823285#c0: STR: 1) Open a private tab and start a download 2) Close the private tab The download remains in the Android notifications list, stuck at whatever % it was when the private tab was closed. Even worse, clicking it does nothing, and it stays in the notification bar without any way to get rid of it (even clearing the X to close all notifications doesn't work).

This keeps track of all all private downloads and cancels their notifications when the last private context is closed.

This bug is the low risk, second part of the "notifications get stuck" fix for private browsing (see comment 0).
