Title: Extract the reason that JSON.parse was failed.

JSON.ParserError occurs if casting has failed when too large column value was given to load.
This behavior is valid, but groonga returns 2 json data joined by LF in this case.

So, this patch extracts failed reason from 1st part of the json data.
