Make sure the .env.local.php is loaded correctly

[Toflar]

This fixes a few issues:

• if you had a .env.prod.local for example, this was never loaded because of the missing second self::loadEnv() call
• the .env.local.php was never correctly loaded either
• we now use Dotenv::populate() which correctly populates all variables instead of our manual old code
• Passing false as argument to Dotenv is deprecated, this is not needed anymore

the .env.local.php was never correctly loaded either

If the file exists, it was loaded and the process was stopped. This means that if the file was dumped from the dev environment, the .env.loca.php would contain the dev configuration, and this env would always be loaded (regardless of the parameter given in the method).

Thank you @Toflar.

I tested with

• .env
• .env.local
• .env.prod
• .env.prod.local

While not having APP_ENV=dev in my .env.local. Only the .env and .env.local files where loaded.

Upon further inspection I noticed, that the "default" for APP_ENV is now jwt instead of prod after this PR.

We are setting jwt as the $defaultEnv here:

contao/manager-bundle/src/HttpKernel/ContaoKernel.php

Line 223 in e1f41c7

self::loadEnv($projectDir, 'jwt');
