Add fields for members and subgroups to the group index

When groups are read from NoteDb, we won't be able to quickly determine
the parent groups of a group or the groups in which an account is a
member. For this reason, we need to add those details to the group index
so that we can perform those lookups from the index.

For convenience and testing reasons, we also expose them via the query
interface.
