Describe the bug Steps to repoduce:

1. Installed verison 7.x-3.18 of 'redis' module.
2. Default docker-compose.yml
3. Custom docker-compose.override.yml
4. Added to settings.php code from https://github.com/wodby/docker4drupal/blob/master/tests/7/test.settings.php

$contrib_path = is_dir('sites/all/modules/contrib')
  ? 'sites/all/modules/contrib'
  : 'sites/all/modules';

if (file_exists($contrib_path . '/redis')) {
  $conf['redis_client_base'] = 0;
  $conf['redis_client_interface'] = 'PhpRedis';
  $conf['lock_inc'] = $contrib_path . '/redis/redis.lock.inc';
  $conf['path_inc'] = $contrib_path . '/redis/redis.path.inc';
  $conf['cache_backends'][] = $contrib_path . '/redis/redis.autoload.inc';
  $conf['cache_default_class'] = 'Redis_Cache';
  $conf['cache_class_cache_form'] = 'DrupalDatabaseCache';

  $conf['redis_client_host'] = 'redis';
  $conf['redis_client_port'] = '6379';
  $conf['redis_client_password'] = 'bad-password';
}

5. Refresh page leads to endless loading which ends by timeout.

Notes: When login to redis container, ran 'redis-cli' and then 'keys *' then it shows that some cache data already stored.
