You could make these fake smarter in the future and just send Added/Removed
based on the adapter that's made present.

Also it's generally better not to add any fake logic until you have a proper use
case for them (i.e. unit tests), so you could just leave these methods empty and
add the proper code later when you're adding test cases to device/bluetooth.
It's not great when your current fake logic ends up not suiting your test case
and you end up fixing these up anyway.

This fake logic is actually good reference to me as to how the real system would
react (based on all the comments by jamuraa@). I don't mind re-working the logic
once I write the tests that utilize this. I'll ensure that this logic matches
what we need in the next CL.
