Configuration files are loaded incorrectly

[SAMERkab]

Configuration data is incorrectly saved in the $config array in loadConfiguration() due to wrong use of array_merge_recursive(). array_merge_recursive() combines a set of arrays into one array by copying all entries from the input arrays into the result array. When two entries have identical keys, an array of the values of both entries is created and assigned to that key in the result array.

private function loadConfiguration(array $searchPaths)
    {
        $config = [];
        foreach ($searchPaths as $file) {
            if (file_exists($file) && is_readable($file)) {
                $config = array_merge_recursive($config, $this->loadConfigurationFromFile($file));
            }
        }

        $this->gitlabUrl = $config['gitlab_url'];
        $this->gitlabUserUsername = $config['gitlab_user_username'];
        $this->gitlabUserEmail = $config['gitlab_user_email'];
        $this->gitlabAuthToken = $config['gitlab_auth_token'];
    }

Solution: Use array_merge() instead of array_merge_recursive().
