Allow comment query results to be limited to comments with comment_post_ID = 0.

Browse Source 
Previously, this was not possible due to an overly broad `empty()` check.

Passing `null`, `false`, or `''` to 'post_id', or omitting 'post_id'
altogether, will continue to return comments regardless of `comment_post_ID`,
as before. Passing `0` or `'0'` will limit results to comments with no
associated post.

Props danielbachhuber.
