Steps to reproduce

1. I started a fresh new Rails application using:

rails new . --api --database=postgresql

2. I inserted dotenv-rails into the Gemfile:

group :development, :test do
  gem 'dotenv-rails'
end

3. I setup two environment file .env.development and .env.test with:

DATABASE_URL=postgres://val@localhost/myapp_dev

and

DATABASE_URL=postgres://val@localhost/myapp_test

respectively.

4. Run rake db:create.

Expected behavior

I am expecting rake db:create to load .env.test environment variable as pointed by the README.

Example:

Created database 'myapp_dev'
Created database 'myapp_test'

Actual behavior

But I get:

Created database 'myapp_dev'
ERROR:  database "myapp_dev" already exists
STATEMENT:  CREATE DATABASE "myapp_dev" ENCODING = 'unicode'
Database 'myapp_dev' already exists

As you can see, instead of creating the development and test database, it attempts to create the development database twice. Clearly, dotenv is ignoring the .env.test.
