During compilation, we had the following warning which is now fixed
```
==> restarter
Compiling 1 file (.ex)
warning: Logger.__do_log__/4 defined in application :logger is used by the current application but the current application does not depend on :logger. To fix this, you must do one of:
1. If :logger is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs
2. If :logger is a dependency, make sure it is listed under "def deps" in your mix.exs
3. In case you don't want to add a requirement to :logger, you may optionally skip this warning by adding [xref: [exclude: [Logger]]] to your "def project" in mix.exs

This was done by floatingghost as part of a bigger commit in Akkoma.
See <37ae047e16/lib/pleroma/application.ex (L83)>.
As explained in <https://ihatebeinga.live/objects/860d23e1-dc64-4b07-8b4d-020b9c56cff6>

How it fails?

This is based on me setting one up, but I kept it general with mostly linking to other documentation.
The idea is that to just provide some Pleroma-specific info, maybe give some pointers, and point to the right (external) docs.
It used a timer to sleep.
But time also goes on when doing other things, so depending on hardware, the timings could be off.
I slightly changed the tests so we still test what we functionally want.
Instead of waiting until the cache expires I now have a function to expire the test and use that.
That means we're not testing any more if the cache really expires after a certain amount of time,
but that's the responsability of the dependency imo, so shouldn't be a problem.
I also changed `Pleroma.Web.Endpoint, :http, :ip` to `127.0.0.1` because that's the setting people typically have,
and I see no reason to do it differently.
Especially since it's an exernal ip, which may come over as weird or suspicious to people.
