test-bookmarks-pushpull.t: don't set bookmark active unnecessarily

The test in question doesn't have anything to do with having an active
bookmark. This change makes the test change the two bookmarks it affects
without making them active. It clears the way for adding a test for
updating to an active bookmark that moved out from under us.
