Hide echo of no categories from get_object_taxonomies

I believe that what you want is show_option_none

show_option_none
(string) Set the text to show when no categories are listed. Defaults to “No categories”.

Proof of concept:

$args = array('include'=>123,'show_option_none'=> '');
wp_list_categories( $args );
