[REGRESSION] db-service v1.12.1 broke deep inserts

[hakimio]

Description of erroneous behavior

Following works fine with 1.12.0 but breaks with 1.12.1:

const result = await INSERT.into('MyService.MyEntity').entries({
  foo: 'bar',
  nestedEntity: {
    bar: 'baz'
  }
});

With 1.12.0 proper result is returned, with 1.12.1 result is 0 and nothing is inserted.
