This reverts 1862c3d9ab.
The "time" field was added in the APNs payload to log
"Remote queuing latency".
The client doesn't use this field. Ideally, we should have
removed the field from the payload before sending it to APNs.
We no longer log "Remote queuing latency", so it's safe to
remove it from the APNs payload.
Only FCM payload will have this field as it is used by android
clients.
