devicesChangedEventStream returns empty sets on first load

[adigladi]

Seems similar to #63 .

Currently when starting the app and initializing a listener to the devicesChangedEventStream, when the first event is triggered, the sets are empty. After that first event everything works as normal. E.g I start the app with no headphones, after init I plug in headphones and an event is triggered with no devices added and no devices removed. But when I plug them out, then the list shows correct added/removed devices.

Same issue here. audio_session: ^0.1.17 iOS: 15.2

Only the first event contains the empty sets.
