 Currently `wp_insert_comment()` allows the insertion of a comment with no
 post `ID` specified, or with an invalid post `ID` (one that does not
 correspond to a valid post).

 So the following use case:

 {{{
 wp_insert_comment( array() );
 }}}

 creates a comment with post `ID` `0`, and the following use case:

 {{{
 wp_insert_comment( array('comment_post_ID' => 999999) );
 }}}

 creates a comment with post `ID` of `999999` (considering that `999999`
 does not correspond to a valid post).

 Both of the created comments are invalid, as they "hang" in the middle of
 nowhere, attached to non-existing posts, and displaying weird results and
 errors in the Comments administration screen.

 In order to fix this, the function should check the `$comment_post_ID`,
 and if it is invalid, `false` should be returned.
