Some conversations have multiple actions with no parent

In particular, there's about 1% of comments that have a section heading introduction at the same time as a comment addition (same revision & timestamp, but separated into 2 actions), e.g.

{  
   "96983583.202.24":{  
      "id":"96983583.202.24",
      "comment_type":"COMMENT_ADDING",
      "content":" From the other notes from other Wikipedia notes, I'm not the only one who questions your judgment.",
      "timestamp":"2006-12-28 19:35:53 UTC",
      "status":"just added",
      "page_title":"User talk:Jinxmchue",
      "user_text":"Sotaman",
      "parent_id":""
   },
   "96983583.24.24":{  
      "id":"96983583.24.24",
      "comment_type":"SECTION_CREATION",
      "content":" ==Bluffs? You see bluffs? I'll call your bluff==",
      "timestamp":"2006-12-28 19:35:53 UTC",
      "status":"just added",
      "page_title":"User talk:Jinxmchue",
      "user_text":"Sotaman",
      "parent_id":""
   },
   "96983583.48.24":{  
      "id":"96983583.48.24",
      "comment_type":"COMMENT_ADDING",
      "content":" Here, visit this link: [EXTERNA_LINK: http://images.google.com/images?q=bluffs&ie;=UTF-8&oe;=UTF-8&rls;=org.mozilla:en-US:official&client;=firefox-a&sa;=N&tab;=wi] Then tell me you see bluffs around Montevideo, much less (as you earlier characterized them) \"spectacular\" bluffs. Sorry if my standards for geographical features are a bit higher than what's seen in your minds eye.",
      "timestamp":"2006-12-28 19:35:53 UTC",
      "status":"just added",
      "page_title":"User talk:Jinxmchue",
      "user_text":"Sotaman",
      "parent_id":"96983583.24.24"
   },
   "97139226.240.240":{  
      "id":"97139226.240.240",
      "comment_type":"COMMENT_ADDING",
      "content":" :Higher?  More like narrower.  Bluffs are not just sheer cliffs.  As I said, check the dictionary.",
      "timestamp":"2006-12-29 14:41:34 UTC",
      "status":"just added",
      "page_title":"User talk:Jinxmchue",
      "user_text":"Jinxmchue",
      "parent_id":"96983583.202.24"
   }
},

We now handle this in the JS by inferring who should be the parent, but we might want to consider doing this in the python in future.

Hmm, this is actually a bug case in the reconstruction code, will fix it. The action is supposed to be divided into a title and a context edit, but the context edit should be linked to the title edit with a reply link.
