Exec[iptables-aggregate]: '[' is not qualified and no path was specified.

issue with the master branch ( ca206e6 ) when attempting to use snippets

  class { 'iptables':
    use_snippets => true,
  }
  iptables::snippet { '01_common_iptables_rules':
    iptables_content  => epp($ipv4_template_path, { 'ipver' => 'v4' }),
    ip6tables_content => epp($ipv6_template_path, { 'ipver' => 'v6' }),
  }

error:

Error: Parameter onlyif failed on Exec[iptables-aggregate]: '[' is not qualified and no path was specified. Please qualify the command or specify a path. (file: /etc/puppetlabs/code/modules/iptables/manifests/exec.pp, line: 17)

something is off with

    exec { 'iptables-aggregate':
      command => "/bin/cat ${iptables::snippet_dir}/*.v4 > ${iptables::iptables_aggregated_file}",
      umask   => '0077',
      # only if missing/empty aggregated file or if aggregated file is older than snippet dir
      onlyif  => "[ ! -s '${iptables::iptables_aggregated_file}' ] || [ '${iptables::iptables_aggregated_file}' -ot '${iptables::snippet_dir}' ]",
    }

it appears that the bash test that is occurring in the onlyif does not work properly
