<h3>Log Message</h3>
<pre>Fix some undefined index notices related to Comment unit tests:
* There are several places where a `$_POST` index was unchecked before setting a variable
* In `wp_notify_postauthor()`, `$comment` was being returned null, but its properties were being accessed.
* In `check_ajax_referer()`, 3 different values can be checked for nonce on `$_REQUEST`, but only 1 had an `isset()`

See <a href="http://core.trac.wordpress.org/ticket/25282">#25282</a>.</pre>
