Fix a race condition that caused device states to become incorrect for hints.

The problem here is that the hint processing code was subscribed to the wrong
event type.  So, it started processing state for a hint too soon, before the
device state cache had been updated.

Also, fix a similar bug in app_queue, as it was also subscribed to the wrong
event type.

(closes issue #14461)
