🔥[v6] Firestore onSnapshot on a single document is always undefined

[FoodlyEric]

Issue

When querying a single document using onSnapshot the document and exists property is undefined. Using get instead of onSnapshot works fine. Using onSnapshot on collection works fine too.

firestore().collection('Users').doc(userId).onSnapshot(snapshot=> {
  // these are both undefined
  console.log(snapshot.exists)
  console.log(snapshot.data())
})

Thanks for reporting! One line fixes this here. Will get sort a release out.

I'm more confused how the tests didn't pick this up to be honest so I'll be checking that out.
