#40975: 'Empty Spam' and 'Empty Trash' comment buttons not displayed on mobile

----------------------------+-------------------
 Since [26134], top navigation for list tables is not displayed on mobile,
 which means that 'Empty Spam' and 'Empty Trash' buttons were only
 displayed in bottom navigation.

 Since [40297], these buttons are not displayed in bottom navigation either
 (on both mobile and desktop) if there's only one page of comments in
 Spam/Trash, because `$this->extra_items` is empty, `$this->items`
 [source:tags/4.8/src/wp-admin/includes/class-wp-comments-list-
 table.php?marks=458#L445 ends up empty too] in `::display()`, so
 `$this->has_items()` returns false.

 The lack of the button also causes the `%s items` string to overlap with
 the search bar, see the screenshot.

 If there are two or more pages of comments in Spam/Trash, the buttons are
 displayed as expected.
