wp_update_comment() can't update the comment_post_ID

[tyxla]

The current implementation of wp_update_comment() does not allow to change the comment_post_ID - the ID of the post that the comment is posted to. Even if comment_post_ID is passed to the array parameter, it is being stripped off the database update query.

So, the following code:

wp_update_comment(array(
	'comment_ID' => 1,
	'comment_post_ID' => 2,
	'comment_content' => 'test text here',
));

will not change the comment_post_ID to 2, even if 2 is a valid post ID.

Allowing the comment_post_ID to be updated, and if passed, make sure that it corresponds to a valid post ID. Adding a unit test assertion in Tests_Comment::test_wp_update_comment() for that functionality.

Allow comment_post_ID to be passed to wp_update_comment(), so that a comment can be moved to a different post.
