Exist duplicate conf file while development mode is enabled.

When development mode is enabled the file 'config/development.config.php.dist' is copied to 'config/development.config.php' . This file [set value to 'config_glob_paths'](https://github.com/zfcampus/zf-apigility-skeleton/blob/master/config/development.config.php.dist#L16) that make the file 'config/autoload/global-development.php' useful for conf while in development mode.

At the same time, when development mode is enabled, the file 'config/autoload/global-development.php' is copied to 'config/autoload/development.local.php', coping  a file that already was referenced (taking into account) by the conf processing logic while in development mode, so the content of the file
'config/autoload/global-development.php' will be processed twice.
