fix(db-mongodb): sort by fields in relationships with draft: true (#12387)

Fixes sorting by fields in relationships, e.g `sort: "author.name"` when
using `draft: true`. The existing test that includes check with `draft:
true` was accidentally passing because it used to sort by the
relationship field itself.
