Invoke-IcingaCheckScheduledTask emits invalid perfdata: lastruntime=1999/11/30 00:00:00;;;;

[Al2Klimov]

First of all: yes, this is a framework issue, despite the specific plugin. At least I have the following reason to assume that:

1. I install IfW 1.12
   • Update-Icinga -Name plugins -Version 1.12.0 -Force
   • Update-Icinga -Name framework -Version 1.12.3 -Force
2. I run Invoke-IcingaCheckScheduledTask for a specific task (admin PS)
3. Perfdata: ...::nextruntime'=133843696470000000s;; ... ✅
4. I update the framework: Update-Icinga -Name framework -Version 1.13.0
5. I run Invoke-IcingaCheckScheduledTask again (admin PS)
6. Perfdata: ...::lastruntime=1999/11/30 00:00:00;;;; ... 🛑

AFAIK, "1999/11/30" is not a valid perfdata value.

Neither Update-Icinga -Name framework nor Update-Icinga -Name plugins help.
