Stream to List conversion

Changes the result for queries that return collections to a Future.

Originally it made sense to use a Stream because of the filtering but since Shellstone inserts the filter for you into the map before it goes to the List there doesn't seem to be a compelling reason to continue to return a Stream as it is not as pleasant to work with. See closed issue #36 for more information. Streams don't make sense as soon as a related cross source collection is part of the model retrieval so this will keep it consistent.
