When a user accepts an invite with an email address that matches a group
which automatically awards its members Trust Level 2, a race condition might happen
when the 'send_advanced_tutorial_message' job runs.
That job is enqueued inside the 'user_promoted' event which is triggered inside a
transaction on the user record. If the job runs before the transaction is done,
the user record is invisible and this generates an exception.
FileHelper.download requires a string not a URI. I also found another
instance of using open-uri directly and swapped it out to use
FileHelper.
I also updated it to not `read` a file if it comes back nil.

By requiring open-uri this will fix the following error:
```
NoMethodError (private method `open' called for #<URI::Generic...
```
also switched to the shorter syntax and removed default options. Since
ruby 2.4 redirect is on by default.
To eliminate a DDOS attack vector, we're taking the following measures:
The endpoint will be rate-limited to 3 requests every 60 seconds (per user).
A 24 hours max-age cache header is sent with the response.
The route will be hijacked to generate the certificate in the background.
AppEvents was always a service object in disguise, so we should move it
to the correct place in the application. Doing this allows other service
objects to inject it easily without container access.
In the future we should also deprecate `this.appEvents` without an
explicit injection too.
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
Advanced trigger is currently broken on:
ca
es
et
fr
he
it
pt_BR
And that is because the translation levels for the plugin are kinda low, so I would guess it's broken for half the languages.
Since we have only two tracks for a while now, a quick fix to me is inverting the selectors.
This patch works because the advanced key is "larger" than the new user one.
If a locale has triggers that start with the same word, our regexp will
always end up matching the first trigger. For example,
`start tutorial` and `start tutorial advanced`
To support the change, we have to make the match on triggers more
restrictive. `@discobot quote here` will no longer work like `@discobot
quote`.
