ini files not working with router.php

[DanielRuf]

Bug Report

It seems loading a config file with auto_prepend_file does not work with the router.php file. If I use the internal PHP server without this, it works.

https://github.com/wp-cli/server-command/blob/master/src/Server_Command.php#L90

This works without any problems:

php -c .../.user.ini -S localhost:8080 -t .

Describe the current, buggy behavior

php wp-cli.phar server --config=.user.ini

Describe how other contributors can replicate this bug

• create a .user.ini file with a auto_prepend_file setting
• run php wp-cli.phar server --config=.user.ini
• open the browser
• check if the file is actually executed (add an echo to it)

Describe what you would expect as the correct outcome

The ini file should be loaded and the auto_prepend_file setting should work.
