Add check for the device having "feature face" before requesting the service
Personally, I think it'd be better for the service to return null rather
than throwing an error if it doesn't exisit but according to b/135475155
throwing is WAI.
Test: try running any test that might use ExandableNotificationRow on a
device without face service and see that an exception isn't thrown
