check secrets and ssl in production

[jordimassaguerpla]

If secrets have not been set or ssl, render an error page. This will
prevent running unsafely in production but also provides with a
running application.

The message needs to be rewritten. I'll do that on a separate commit.

Instead of fix_secrets = false and then the if, do:

fix_secrets = true if Rails.application.secrets.secret_key_base == "CHANGE_ME"

The same for fix_ssl. If the variable is not defined it will be nil, therefore evaluating to false anyways ;) Moreover, rubocop is complaining about the final if statement. Instead of doing that, you should:

return unless fix_secrets || fix_ssl

And then proceed with the code.

Moreover, I'd appreciate if you could add documentation to this method :)

I just rebased according to mssola comments

There are still some failures, but it looks like it is a commit that I pushed directly before :/ Thanks 👍
