_get_list_table() should account for the lack of a screen for ajax

If 'screen' is not passed, _get_list_table() will call get_current_screen(), which might trip over hook_suffix not being set, for plugin-initiated ajax requests. We could do a quick check for elseif ( isset( $GLOBALS['hook_suffix'] ) ) to avoid the notice. Better to not pass a screen than an improper or broken one.
