image-device: Delay task completion until device is deactivated

Browse Source 
The earlier image device code tried to hide deactivation from the
surrounding library. However, this does not make any sense anymore with
the early reporting feature present.

This changes the operation to complete only once the device is
deactivated. Also changed that in most cases (except for cancellation)
we wait for the finger to be removed before deactivating the device.
