Backport of #182
The Lookup Operator implementation previously did not free the reference to its lookup keys. This meant that its keys would be kept in-memory if the compiled query was sent to the XQuery Pool for reuse. This PR fixes that issue so that the memory is correctly freed when the query completes execution.
When combined with #177 this closes eXist-db/exist#5375
