#25429: `get_the_category_by_ID` triggers PHP notice on non-existent category

 When calling `get_the_category_by_ID()` with a bad category ID, the
 function internally triggers a PHP notice.  Internally, the function uses
 `get_term()`, which can return `null`. However, the function only checks
 `is_wp_error()` and not null, leading to the following notice:

   Notice: Trying to get property of non-object in /var/www/wordpress/wp-
 includes/category-template.php on line 141
