Describe the bug

When notifyOnNetworkStatusChange is set to true and call refetch, then the network states sticks and always shows loading spinner

To Reproduce Steps to reproduce the behavior:

1. Create queryRef:

this.queryRef = this.readQuery.watch(variables, {
      fetchPolicy: 'cache-and-network',
      // BUG if uncomment next line, then there will be an infinite load when calling refetch
      // notifyOnNetworkStatusChange: true,
      ...readQuery?.options
    })

2. Call refetch

this.queryRef.refetch(variables);

3. Observe loading status

this.querying$ = this.queryRef?.valueChanges.pipe(
      map((x) => x.loading),
      distinctUntilChanged(),
      shareReplay(1)
);

Expected behavior

Then refetch complete network request loading indicator should be false
