Facets not set via set_json for uid predicates

Ok, either docs or implementation are wrong :slight_smile:

In order to set a facet on a uid predicate, you have to nest it inside it and it is returned there as well when querying.

This works as expected:

{
  "uid": "0x1",
  "seen": {
    "uid": "0x2",
    "seen|tag": "example"
  }
}
