Have you tried adding an is_home() to your if() and using your own preferred array of post types?  (If you'll read through the code I would hope it's reasonably obvious that it would only work for author and search pages.)


add_filter( 'parse_query', 'my_parse_query' );
function my_parse_query( $query ) {
      $q = $query->query;
      $is_menu = (isset($q['post_type']) && $q['post_type']=='nav_menu_item');
      if (!$is_menu && is_home() || ((is_author() && isset($q['author_name']) || (is_search() && isset($q['s']))))) {
              $query->query_vars['post_type'] = array( 'post','lesson', 'howto', 'workshop', 'attachment' );
