Fix a bug where if you did a slow search that took too long to calculate the page count, and you had 200 posts per page, then we would show page 5000 as the last page of the search. This was because we were artificially returning 1,000,000 as the post count to signal that the count timed out, but at 200 posts per page this would show 5000 as the last page of the search.
