Description

Order direction cannot be specified when using the QueryBuilder. Consider the following:

(new SelectBuilder()).addWhere("?a", "?b", "?c").addOrderBy("DESC(?a)").buildString()

Actual:

SELECT  *
WHERE
  { ?a  ?b  ?c }
ORDER BY ?DESC(?a)

Expected:

SELECT  *
WHERE
  { ?a  ?b  ?c }
ORDER BY DESC(?a)

It seems the QueryBuilder assumes that only a field name will ever be passed and tried to be 'helpful' by prepending a '?' if it is omitted.
