Fix crash on shutdown when update in progress.

The ActionProcessor destructor normally calls the ProcessingStop method
on the delegate. For the UpdateAttempter this call re-schedules a new
update attempt on a half-destroyed update_attempter instance, crashing
update_engine on SIGTERM when the ActionProcessor was running.

This patch inhibits the ActionProcessor from notifying the delegate of
the processor stopping when destroying the update_attempter instance.
It also fixes the declaration order of the dbus_adaptor_ and disables
its usage during daemon shutdown.
