Deflake TestSyncDeploymentDeletionRace

Browse Source 
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
```
