Check_MK Werk 0438: Remove test-code, Micro Core only worked once per host

ID: 0438 Title: Remove test-code, Micro Core only worked once per host Component: Core & Setup Level: 2 Class: Bug Fix Version: 1.2.5i1 Due to remaining test-code the file <tt>/tmp/dev_null</tt> was created instead of <tt>/dev/null</tt>. That way only the first site using Check_MK Micro Core was working. This has been fixed.
