Comments List Table:

* In a view that initially has comments, but they get removed due to user actions: show the `No Items` row instead of bombing out and showing nothing (which looks broken)
* To accomplish this, in `WP_Comments_List_Table::display()`: call `->display_rows_or_placeholder()` instead of `->display()`
* Listen for the end of row `.fadeOut()`s if necessary using jQuery Promises

Fixes #11200.
