Custom validation closure does not exist and is bypassed

[dvuckovic]

Following custom validation closure tutorial in the documentation results in a console error.

import { VueFormBuilderPlugin } from 'v-form-builder';

function myCustomValidation(fieldValue: string, valuesContainer: {}) {
  return fieldValue === 'Seth Phat';
}

Vue.use(VueFormBuilderPlugin, {
  validationClosures: {
    'sethPhatCustomCheck': myCustomValidation
  }
});

Custom Validation Closure sethPhatCustomCheck does not exists. Bypassed

It seems like the custom closure is ignored, i.e. it doesn't get applied or is not reachable by the validator code.
