 In wp_list_categories(), we detect the current category using the queried
 object. But, we don't check if the taxonomy of the queried object matches
 what we're displaying with wp_list_categories(). Clearly, the current
 category for purposes of listing categories needs to be the same taxonomy.

 A get_term() call in Walker_Category will end up failing and we'll end up
 with warnings for trying to access non-existent properties. I traced that
 up the stack to here.

 Also adding in is_tag() to the current term check because there's no
 reason why someone can't use wp_list_categories() for any taxonomy AFAIK.
