 `get_term()` can return `null`, but `wp_update_term()` checks `$term` for
 only a `WP_Error` before proceeding as if it has an array. This can lead
 to a warning in `array_merge($term, $args)` and a notice in `wp_unslash(
 $args['name'] )`.

 The attached patch adds a check for `null` and a unit test.
