Merge pull request #138 from Icinga:fix/use_correct_conversion_functions_for_tcp_plugin

Fix TCP plugin, use Convert-IcingaPluginThresholds

Instead of using `ConvertTo-SecondsFromIcingaThresholds` we should use `Convert-IcingaPluginThresholds` for converting our plugin thresholds for `Invoke-IcingaCheckTCP`.
