0.20.2: The Integration Outage Release (Bugfix)

Bugfix for 0.20.1.

Fixed

An integration outage now behaves like a broker or bridge outage everywhere, not only on the event bus. The to-do row for a downed integration carries the time it went down, and the phone push announcing how many devices it took with it is sent once the outage settles. Before this fix the outage event fired and the affected devices were correctly held back from individual reporting, but the row read "is not reporting" with no time, and the push never left.
