Using `dotenv/load` causes double loading (and logging) of env when using rails

[fsateler]

On a regular rails application, that requires dotenv/load, env is loaded twice: once at dotenv/load time and once at rails initialization.

% cat test.rb
require 'rails'
require 'dotenv/load'

require_relative 'config/environment'

% bundle exec ruby test.rb
[dotenv] Loaded .env.development.local
[dotenv] Loaded .env.development
[dotenv] Loaded .env.development.local
[dotenv] Loaded .env.development

I believe this is because the rails initializer is inconditional:

dotenv/lib/dotenv/rails.rb

config.before_configuration { load }
