Fix small bug when image loaded for first time

  When an image was loaded for first time, and no annotations exist, the app
would freeze because of 404 error. Fix that.
  
232232 if(jqxhr.status === 404) { //annotations don't exist for this image
233233 console.log('annotations don\'t exist for this image. Create one!');

235 swtr.appView.$overlay.hide();
236 swtr.appView.helpview.step(2);
235237 }
