is_singular is being called on _close_comments_for_old_posts

[luis.ferro]

wp-includes/comment.php (as of version 3.2.1)

Line 1965 calls for is_singular when on certain situations, the query was not yet performed, generating the following error:

Notice: is_singular was called incorrectly. Conditional query tags do not work before the query is run. Before then, they always return false. (This message was added in version 3.1.) wp-includes/functions.php on line 3501

The message pointing to functions.php is not very helpful either, but nothing that a debug_backtrace doesn't sort out.

Use the query object method instead

[kawauso]

Attached patch uses the is_singular() method of the query object that triggered 'the_posts' hook rather than the function which relies on $wp_query.

In [18836]:

Pass the query object to _close_comments_for_old_posts() so that is_singular is checked for the proper query. Props kawauso. fixes #18109
