Support init

[ogarcia]

Summary

I was trying to create a new rustic/restic repository directly in rustic_server and it is not possible.

What happens

Steps to reproduce:

1. Start the server rustic-server -p /var/lib/rustic-server.
2. Create a sample .htpasswd with the user user and password patata.

   user:$2y$10$Qr3zoxzhcA17B0D9EHz1VO3Cufk3Klsez9r8uI6ahE2uhDlIu8jMi
   

3. Set the environment variable to access the repository export RESTIC_REPOSITORY="rest:http://user:patata@localhost:8000/server_repo"
4. Perform restic init
5. After entering the desired password for the new repository the following error appears:

   Fatal: create key in repository at rest:http://user:***@localhost:8000/server_repo/ failed: unexpected HTTP response (500): 500 Internal Server Error
   

What I expected to happen

That the init command worked without problem and created a new repository.
