doc.fullName does not work as Livetable column because the JSON returns doc_fullname

When asking for the column "doc.fullName", it is properly used in the LivetableResultsMacros query, but, when returning the result as JSON, doc_fullname is used instead of doc_fullName and this is not expected by the client side livetable.

This bug seems to be as old as Livetable itself (over 3 years), maybe this property has never been used.

The solution would be to fix the JSON and return doc_fullName instead of doc_fullname.
