"return to normal view" from answer link doesn't preserve sort order

Reproduce steps (from this comment thread):

1. Follow a direct link to an answer to a question with more than 1 answer.
2. Sort by "Active".
3. Click on "return to the normal view".
4. See sort order has returned to "Score".

The text in the "this is a direct link and out of order" message is different depending on the currently-selected sort, so we should be able to grab that sort and pass it through in the "return to normal view" link.
