write tests for UrlFieldValidationRule

Adding patch for UrlFieldValidationRule test. Changes are

1> Created test.
2> Added dependencies module
protected static $modules = ['node', 'field_validation', 'path_alias', 'user'];

3> Replaced patch validator function inside UrlFieldValidationRule.php.

-          $flag = \Drupal::service('path.validator')->isValid($normal_path);
+          $flag = \Drupal::service('path.validator')->getUrlIfValidWithoutAccessCheck($normal_path);

Good work.

1,do not change the code of the validator:

-          $flag = \Drupal::service('path.validator')->isValid($normal_path);
+          $flag = \Drupal::service('path.validator')->getUrlIfValidWithoutAccessCheck($normal_path);

If you think this is bug, you can create another issue.

isValid is OK for most of use case. Drupal 7 version field validation use the similar function which perform a access check.

2, maybe you do not need to install user module， if validate an internal path, we could use "/node" instead of "/user/1",

3, Added dependencies module

protected static $modules = ['node', 'field_validation', 'path_alias', 'user'];

I am not familar with Drupal test. Is it possible override it in UrlFieldValidationRuleTest instead of FieldValidationRuleBase.

path_alias is only used by this test.

Thanks for the review and suggestion. Sharing new patches with suggested improvements. Considered points 1 , 2 and 3.
