In Spec we were creating two topics:
```ruby
fab!(:topic) { Fabricate(:topic, category: category) }
fab!(:topic2) { Fabricate(:topic, category: category) }
```
Because we didn't set title explicitly it was using sequence from Fabricator
```ruby
title { sequence(:title) { |i| "This is a test topic #{i}" } }
```
If you have two titles `This is a test topic 9` and `This is a test topic 10` Spec testing if topics are sorted will fail. Therefore, we should explicitly set topic title when creating test instances to avoid that randomness.
