Don't send notifications about private topics which users don't have access to

[maxceem]

We introduced Private Topics which are only visible for non-customer users.

But if we create such private topics, customer user will still get notifications about them, even though they don't have access to them and cannot see them:

I guess we shouldn't create notifications about private topics, customer users don't have access to.

This one seems similar to #2972, however, I think we need to do some code changes to fix this i.e. I don't think we can get it fixed via config changes only.

Good catch again @maxceem

@vikasrohit this is fixed in topcoder-platform/tc-notifications#117

Verified.
