[Bug] deeper projections

[st0ffern]

after this commit 1b26bf47 deeper projections dont work.

example:

HouseTC.addRelation(
  'people',
  () => ({
    resolver: UserTC.getResolver('connection'),
    args: {
      filter: (source) => ({ 
        _operators: {
          _id: {
            in: source.peopleIds.map(p => p.people) || []
          }
        } 
      }),
    },
    projection: { peopleIds: { people: true } },
  })
)
