Fixed comment parsing, translation json does not always contain a body field ("3").

**Example comment (anonymised):**
{"3":"1392410977213","2":"Jon Doe","10":true,"1":"gp:XXXXXXXXXXXXXXX","7":"1.0.0.0","6":100,**"5"**:{"3":"Booom","2":"Muito bom.","1":"pt_BR"},"4":4,"8":{"3":"Manufactor","2":["Device"],"1":"xxxxx"},**"11"**:{"2":"Very good.","1":"en-US","4":"pt"}}

The last part under PARENT:"11" does not contain a CHILD:"3" which would be the translated comment body.
But the source, PARENT:"5" has a CHILD:"3" with the text "Booom", which is missing in the translation.
If we google translate from **pt** to **en** source and translation are the same, this could be the explanation.
