ei: add receiver handling for empty/flushing frame events

Browse source 
Where the sender sends empty frame events, or a device event without a
subsequent frame events ensure that event is filtered or emulated in our
event queue.

Note: because of our sender filters, we cannot actually test
this, at least not easily. Let's hope it works.
