IsInCalendarSyncInterval interrupts all delete operations
everytime i delete a calendar-item, i get this erro in my z-push.log:
07/07/2017 14:35:53  [WARN] [USERNAME] /usr/share/z-push/backend/kopano/importer.php:262 hex2bin(): Hexadecimal input string must have an even length (2) 07/07/2017 14:35:53  [WARN] [USERNAME] MAPIUtils->IsInCalendarSyncInterval: Message is OUTSIDE the synchronization interval 07/07/2017 14:35:53  [WARN] [USERNAME] ImportChangesICS->isModificationAllowed('S2c099:f0bc882a8e0f410aa9765bd325976fe71b6fa8000000'): Message in Calendar is outside the sync interval. Data not saved.
I was able to reproduce the behaviour and created a ticket for it: https://jira.z-hub.io/browse/ZP-1254.
