Wrong vote counts when merging/unmerging topics
I noticed a weird problem with counts of vote when merging topics.
1. As admin of the project, I create two topics.
2. Another single user vote +1 for each of them.
3. I merge the two topics:
Since it's the same user and the same idea, I should get 1 as the total votes.
That's indeed the vote count displayed just after the merge.
4. But if I refresh the page, then I see 2 as the vote count (the same single voter appears twice in the voters stats)
5. If I unmerge the topics, then the first one gets back +1
but the second one gets +2 votes (the real voter, and one anonymous!)
I made this test twice to be sure. Something's wrong!
