Framework: stop rethrowing remote exception

It makes no sense to rethrow a remote exception as this means that the
bluetooth became off in the midle of the call and we already gracefully
handle the case when the bluetooth is not available.

Test: m Bluetooth | this logic is edge case and goes untested
Flag: Exempt, global refactor to follow good practices
