Description

Using Leaks, it's possible to see that when we use the whereField, there is a memory leak being created. We saw it in several and different calls, all of them the Leaks tool points to the whereField.

Reproducing the issue

1. Adds Firebase Firestore to the project
2. Read documents from a Collection and filter some results using the whereField method from FIRQuery
3. Launch App
4. Observe memory leak using Leaks tool

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

@jorgefrazaocosta Does this happen in version 10.15.0? We suspect maybe this might have been introduced in 10.16.0.

[jorgefrazaocosta]

@tom-andersen Indeed. It doesn't happen in version 10.15.0; I can see it using 10.16.0.

I am assigning this issue to @milaGGL who is more familiar with this part of the code.
