requires muxinc/media-chrome#1024

• fixes an issue where the .error object could be null when the error event is dispatched.
  this was introduced when we started calling initialize() function deferred in mux-video I believe.
  this is fixed by saving the error state each time before we dispatch the error event.
• the warning API is not implemented because after closer inspection we don't really do much with non-fatal errors.
  the only thing is doing a console.warn here:
  

  elements/packages/mux-player/src/index.ts

  Lines 461 to 465 in 1e1f24a

  	logger.warn(error);
  	if (error.data) {
  	logger.warn(`${error.name} data:`, error.data);
  	}
  	return;

  
  we can easily do that in playback-core if we want?
