Review Comment:
With the following group
- Group A with topics a and b
- Group B with topics c and d
`topicsToCheck` will be `[a, b, c, d]` and the authResult will be something
like `[ALLOW, ALLOW, DENY, DENY]` and `authorizedTopics ` will be `[a, b]`.
Then we go through (A, B) where A has all topics in `authorizedTopics` and B
doesn't. So we remove B from the response.
