Checkmk Werk 15260: Fixed rescheduling of non-existent service

ID: 15260 Title: Fixed rescheduling of non-existent service Component: Livestatus Level: 1 Class: Bug fix Version: 2.2.0p9 When a Livestatus query with a "WaitObject:" line for a non-existent service was sent to the monitoring core, a crash happened. This could e.g. be triggered by direct Livestatus queries or via a "Reschedule" in the GUI under certain circumstances. This was a regression in 2.2.0 and has been fixed.
