If the NTP client rejected one of its peers as a falseticker, the corresponding NTP Peer service went UNKNOWN with ValueError: 'summary' must be non-empty str or None and produced a crash report instead of a result. The check yielded the CRIT result for that peer without any text.

The service now reports State: falsetick as the reason for the CRIT, matching how the other peer states are shown.
