Close internal iterator for sequence returned by to-statements implementation of RepositoryConnection

[lkitching]

The to-statements implementation of RepositoryConnection returns a lazy sequence backed by an internal org.eclipse.rdf4j.repository.RepositoryResult. This class contains a close which should be called when the internal sequence has been fully realised or in case of an error.

Agreed we should close this, but does this manifest itself as an error or a bug at all? What symptoms does this have?

[lkitching]

I'm not aware of any issues, no.
