Alignment.
Do not clear the wait or hbinterval values.

If they change, we catch it later on and update it anyway. Clearing
it here wipes out the cached hbinterval when a EAS 12.1+ client
doesn't use the hanging SYNC, but instead still uses PING.
Add device's currently cached heartbeat interval to the device display.
