Firestore - collectionChanges function not emitting empty array when not elements present in queried collection

**Angular:**
13.3.11

**Firebase:**
9.8.4

**AngularFire:**
7.4.1

**Other (e.g. Ionic/Cordova, Node, browser, operating system):**
Node: 14.19.0
Maxc OS: 12.3.1
Chrome (latest)

### How to reproduce these conditions

`
const elements = [1,2,3];
`

`
const surveyReferencesQuery = query(
collection(
this.afs,
'surveyReferences'
) as CollectionReference,
where('companyId', 'in', elements)
);`

`
return collectionChanges(
surveyReferencesQuery
).pipe(
tap((c) =>
console.log(
'collectionChanges',
c.map((s) => [
s.type,
s.doc.id,
s.doc.data(),
])
)
)
);`

### Expected behavior

Should emit empty array

### Actual behavior

Not emitting anything until documents in collection

Start at the collectionChanges entry point and reproduce the provided Firestore query with an empty surveyReferences collection. Compare the observable's initial behavior with the expected empty-array emission; done means the query emits an empty array before matching documents exist.
