Environments can not be deleted

When cloning the environment acquia_search_server_1, the clone name is acquia_search_server_1_0.
As the additional servers contain the same substring as the name (acquia_search_server_1), we can not delete them.

In acquia_search.module :

define('ACQUIA_SEARCH_ENVIRONMENT_ID', 'acquia_search_server_1');

function acquia_search_environment_delete_access($environment) {
  if (strstr($environment['env_id'], ACQUIA_SEARCH_ENVIRONMENT_ID)) {
    return FALSE;
  }
  // Fall back to the original check.
  return user_access('administer search');
}
