Title: Fixed a SEGV caused by touching uninitialized qualRoot->childNodes.

Fixed a SEGV happened while executing search queries repeatedly.

When repeating search queries, uninitialized qualRoot->childNodes sometimes had non-zero/non-null value, and it caused a SEGV in deparseBoolExpr() and lappend().

So, qualRoot and its childNodes must be initialized before being touched in deparseBoolExpr().
