Why this change?
Before this change, the new navigation item in the topic list will be
hidden when there are no new or unread topics for the user. We have
started to find this behaviour confusing UX wise so we decided to stop
hiding it.
Using min_trust_to_create_topic and create_topic_allowed_groups together was part of #24740
Now, when plugins specs are fixed, we can safely remove that part of logic.
The most common thing that we do with fab! is:
fab!(:thing) { Fabricate(:thing) }
This commit adds a shorthand for this which is just simply:
fab!(:thing)
i.e. If you omit the block, then, by default, you'll get a `Fabricate`d object using the fabricator of the same name.
Why this change?
Prior to this change, dismissing unreads posts did not publish the
changes across clients for the same user. As a result, users can end up
seeing an unread count being present but saw no topics being loaded when
visiting the `/unread` route.
