Duplication of topics in "Izbrannom" in the profile

Not that a very terrible bug, but still the most innocent errors can lead to the most unexpected consequences.

There is such a topic (do not consider it PR): habrahabr.ru/blogs/i_am_insane/47912

Even if we take into account the duplicated topic, it turns out a total of 14 posts. However, the amount is shown to be 15.

The header on the Favorites button shows an incorrect number of topics.


PS: All the same it was very mean - to post the discovered bug on Friday night :)
