No need for us to specify our custom teardown hook when Sidebar
component is destroyed when each custom section link is expected to be
its own component and can implement its own `willDestory` hook.
1. Injecting `appEvents` service into `screen-track` was unnecessary as it's already injected into all services (and was causing an assertion error)
2. Return a promise from `sendNextConsolidatedTiming()` (no need for `await settled()` then)
Also, the change in insert-hyperlink (from `this.linkUrl.indexOf("http") === -1` to `!this.linkUrl.startsWith("http")`) was intentional fix: we don't want to prevent users from looking up topics with http in their titles.
This commit introduces a new plugin API to register
a group of stats that will be included in about.json
and also conditionally in the site about UI at /about.
The usage is like this:
```ruby
register_about_stat_group("chat_messages", show_in_ui: true) do
{
last_day: 1,
"7_days" => 10,
"30_days" => 100,
count: 1000,
previous_30_days: 120
}
end
```
In reality the stats will be generated any way the implementer
chooses within the plugin. The `last_day`, `7_days`, `30_days,` and `count`
keys must be present but apart from that additional stats may be added.
Only those core 4 stat keys will be shown in the UI, but everything will be shown
in about.json.
The stat group name is used to prefix the stats in about.json like so:
```json
"chat_messages_last_day": 2322,
"chat_messages_7_days": 2322,
"chat_messages_30_days": 2322,
"chat_messages_count": 2322,
```
The `show_in_ui` option (default false) is used to determine whether the
group of stats is shown on the site About page in the Site Statistics
table. Some stats may be needed purely for reporting purposes and thus
do not need to be shown in the UI to admins/users. An extension to the Site
serializer, `displayed_about_plugin_stat_groups`, has been added so this
can be inspected on the client-side.
This logic should no longer be triggered. The EMBER_GLIMMER_SET_COMPONENT_TEMPLATE gets removed in recent versions of Ember, which can cause it to accidently trigger and cause layout issues with some plugins/themes.
The `unread_not_too_old` attribute is a little odd because there should never be a case where
the user's first_unread_at column is less than the `Topic#updated_at`
column of an unread topic. The `unread_not_too_old` attribute is causing
a bug where topic states synced into `TopicTrackingState` do not appear
as unread because the attribute does not exsist on a normal `Topic`
object and hence never set.
