Hi there,
I've found that this specific snippet is producing a false negative on older rocket.chat instances.

In my Rocket.Chat instance, I have custom roles set up which are already a few years old.
When looking in the db, they're all missing the protected tag within the db.

I stumbled over this issue, when I wanted to get a specific custom role, but my code failed, saying that it couldn't find the role in question.
Could this code be changed, so that it negates everything? e.g. instead of hard-match protected: false, match for the opposite with the protected: { $ne: true }, I think this should also cover non-existend protected tags like in my case.

Thanks.
