Nest topComments in abstracts

Almost all of a topComment is now nested in an abstract, using IDs to join other objects. The last piece is getting users to be able to joined inside of the `subComments` field `commenter`. The `group` method needs to re-add all fields via `first`, but for now it's easier to debug without all of those there.
