Deflake TestSyncDeploymentDeletionRace

**What this PR does / why we need it**:

The cache was sometimes catching up while we were testing the case
where the cache is not yet caught up.

Before this fix, I could reproduce the failure with the following
command. After the fix, it passes.

```
go test -count 100000 -run TestSyncDeploymentDeletionRace
```

I checked the other controllers, and they all were already not starting informers for the deletion race test. I also checked that the deletion race tests for other controllers all pass with `-count 100000`.

**Which issue this PR fixes**:

Fixes #43390
