Solving a memory leak from LPRuleEngine
Each time a `LPRuleEngine` gets called to find a triple for which a cached
`Generator` exists in `tabledGoals` a new `ConsumerChoicePointFrame` is
registered as a consumer of this Generator.
The leak is that it is never unregistered from the consumer, the solution
was simply to call the unregistering from the `close()` method of the
`ConsumerChoicePointFrame`
