Fix issue with invisible recurring appointments

Fixes that recurring appointments goes invisible
when hit by the failsafe limit.

There is still a hard limit in RecurrenceProcessor,
but at least this limit is applied on a per-event
basis, meaning that it's always possible to create
new recurring appointments without them going invisible.
