Checkmk Werk 12711: ps_check: crash on non-matching enforced service 'State and count of processes'

ID: 12711 Title: ps_check: crash on non-matching enforced service 'State and count of processes' Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Configuring 'State and count of processes' as enforced service with per-process details set to 'text' crashes with unhandled "ValueError: 'notice' must be non-empty str or None, got" if the specified process could not be found. This change avoids this exception by not trying to render a process list without processes found.
