The resulting entity of the awaited #save$ method does not include an id

[lilsweetcaligula]

The resulting entity of the awaited #save$ method does not include an id. It should.

Promisified:

const product = await seneca.make('product')
  .data$({ label: 'Legions of Rome' })
  .save$()

console.log(product)
// outputs: Entity { 'entity$': '-/-/product', label: 'Legions of Rome' }
// the returned entity has no id

Traditional callback-based:

seneca.make('product')
  .data$({ label: 'Legions of Rome' })
  .save$((err, out) => {
    if (err) return done(err)
    console.log(out)
    // outputs: Entity {  'entity$': '-/-/product',  label: 'Legions of Rome',  id: 'j0s5rs' }
    // the returned entity has the id
    return done()
  })

The bug has been first observed during writing of automated tests in the mem-store.
