Describe the bug

In Interpolator.js, function applyRule has:

  applyRule(str, rule, data = {}) {
    const dataToReplace = this.applyData(rule.key, data);
    if (dataToReplace) {
      return str.replace(rule.replace, this.applyModifiers(rule.modifiers, dataToReplace, data));
    } else if (rule.alternativeText) {
      return str.replace(
        rule.replace,
        this.applyModifiers(rule.modifiers, rule.alternativeText, data),
      );
    }

    const defaultModifier = this.applyModifiers(rule.modifiers, rule.key, data);
    if (defaultModifier === rule.key) {
      return str.replace(rule.replace, '');
    }
    return str.replace(rule.replace, defaultModifier);
  }

So, when dataToReplace is 0, str.replace(rule.replace, '') will be returned.

To Reproduce Steps to reproduce the behavior:

parse string /users/{args.userId}/carts/{args.cartId}/entries/{args.entryNumber}, data is

{ 
  args: {
     cartId: '00001017',
     entryNumber: 0,
     userId: 'current'
  }
}

expected result is: /users/current/carts/00001017/entries/0
but what we got is: /users/current/carts/00001017/entries

Expected behavior
