filtering the wrong query

Hi Dinesh –

The form on your site is not accepting my post (probably too many function names 🙂 ), so it’s going here.

The tcp_add_post_types_in_category_and_tag_template function has a series of checks for category and tag, but they are checking the page’s main query rather than the one that was passed. This is breaking sub-queries on category and tag pages.

To fix this, replace is_category() with $query->is_category() and is_tag() with $query->is_tag()

Looks like lots of people are running into issues caused by this bug. Restricting the filter to the main query as some have suggested will help but also limit functionality. I believe the steps above provide a complete fix.
