Anna Henningsen 4c9fb0b706 events: give subclass name in unhandled 'error' message

For unhandled `'error'` events, include the constructor name for
subclasses of EventEmitter, if possible. This makes tracing errors
easier when both creation of the `Error` object and emitting it
happen in code that does not refer back to the event emitter.
