Error starting application if phoenix isn't started when using internal directory

[Daniel Franklin]

I configure SiteEncrypt like so

@impl SiteEncrypt
def certification do
  SiteEncrypt.configure(
    client: :native,
    db_folder: "/tmp/niss_site_encrypt_db_dev",
    directory_url: {:internal, [port: 4002]},
    domains: ["home.danielzfranklin.org"],
    emails: ["[e-mail]"]
  )
end

If I run iex -S mix phx.server everything works fine. If my certificate needs to be renewed and I run iex -S mix I see the following

Erlang/OTP 24 [erts-12.0.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]

This isn't a significant issue, feel free to just close it if you think the fix isn't worth it.

Thanks for the report. I just checked the demo project and I can reproduce it. I think the best option here would be to avoid starting the certification process if the server isn't started.
