SingletonSet is incorrect wrt to a Graph clause

Description

If you have a dataset which includes n named graphs (where n >= 1) the query "select ?g where { graph ?g {} }" should produce n results where each ?g in each result is bound to a named graph identifier. Sesame returns a single empty result because SingletonSet does not have any information about any graph clause it is participating in.
