gkodinov/kgeorge@macbook.gmz 115616381d BUG#14019 : group by converts literal string to column name ...

When resolving unqualified name references MySQL was not
   checking what is the item type for the reference. Thus
   e.g a string literal item that has by convention a name
   equal to its string value will also work as a reference to 
   a SELECT list item or a table field.
   Fixed by allowing only Item_ref or Item_field to referenced by
   (unqualified) name.
