Confluence Questions reputation check is not working for Space questions

Background

It is possible to enable Reputation based permissions for Confluence Questions (CQ). One of the examples of such permissions at work is that the user is allowed to downvote the answer only if user has at least 15 reputation.

While this works OK for global questions, this particular thing is not implemented properly in questions inside space.

Scenario

1. Install CQ
2. Switch on Reputation Based Permissions at General Configuration → Questions for Confluence → Customisation
3. Create question an an answer linked to any space
4. Downvote an answer (with non-admin user that has <15 reputation)

Expected: error message is shown similar to ones for global questions
Actual: answer is successfully downvoted

Additional information

• This works as expected for global questions (not linked to a space)
• There are other things broken (except downvoting). We need to find them all and fix properly.
