Fix switch events for Aqara T2 relay

[trapacska]

Proposed change

1. Fixed event sending, it has 4 args passed in but could only take 3 so the event was not fired.
2. There is an event for each endpoint(1 and 2) when the S1-COM and S2-COM pins are shorted but the original implementation did not separate the events so both S1 and S2 was emitting the same event.

Fixes my issue (partially): #2934
