Get collection failed when using own key

[ckng]

When there are more than one collection with own key, get collection fails. To reproduce:

db.collection('users')
  .add({
    id: 1,
    name: 'Bill',
    age: 47
  }, 'mykey-1')

// or use .doc(key).set():

db.collection('users')
  .doc('mykey-2')
  .set({
    id: 2,
    name: 'Paul',
    age: 34
  })
db.collection('cars')
  .doc('mykey-3')
  .add({
    id: 1,
    name: 'Honda'
  })
db.collection('users').get()
db.collection('cars').get()

Error for both
