Remove references to ViewNotificationService in Dialer

ViewNotificationService ultimately uses a ContactLoader to send
the view notification to the sync adapter. Since ContactLoader is
already a part of ContactsCommon, we just need to create an
instance of a ContactLoader in InCallUI to notify the sync adapter
to download the high res photo.
