fix coalesce_interval_ms not working correctly

[sathyas2023]

#284

The coalesce_interval_ms parameter doesn't get used properly. Spamming axis events (ex: spinning joysticks) causes rates to get very high.

should_publish is being incorrectly overwritten to true in the event loop function.

The PR makes the event loop logic the same as game_controller_node which did not have this issue from my testing.
