fix(device): don't passively listen for updates with 3.4 protocol

Protocol 3.4 devices seem to have problems eventually with passive listening without
sending anything. It is possibly an issue in the tinytuya library, where calling receive
is not just listening, but renegotiating the session key without any command being sent.

Such devices didn't seem to have issues with the 10x/second heartbeats before, so
revert to that for 3.4 devices.

Issue #5136
