#37686 fixed an entire class of devtools protocol bugs that led to protocol desyncs with warnings in the Servo log, but it also removed the warnings, making it harder to spot where our devtools impl is incomplete.
this patch reintroduces a warning whenever some Actor::handle_message() returns Err(ActorError).
Testing: debug logging only, so not really worth testing
